Translate the Terminal and Logs output - #646

## Why

The Open a pull request card, its GitHub sign-in, and the errors main
sends it were plain English in a translated window. This is the #625
batch of #622, which needed the catalog in main from #634.

## What changes

- **The card** (`pull-request-destination.jsx`) wraps every string.
Sentences with a link or code in them use `createInterpolateElement`,
with logins, branches and repository names passed in as elements so they
are never read as markup. The failure messages are a function instead of
a module-level constant.
- **Per-project text** in `project-type.cjs` (`cards.*`) is getters,
read when the card renders. Main's refusal with nothing linked used to
splice the work item's label into a sentence; it is now
`cards.prNeedsWorkItem`, one sentence per project type.
- **Main process:** the sign-in errors in `github-auth.cjs` and the pull
request errors in `github-pr.cjs` are wrapped, including the step labels
passed to `failure()`, which the issue did not list. The "Trunk has
moved" message uses `_n`, and a GitHub failure is composed with `%1$s:
%2$s%3$s` so a translator can change the punctuation. GitHub's own
reason and the bracketed diagnostic for GitHub support stay as they are.

Not wrapped, per #622: the pull request body and the default pull
request title, because they leave the app.

## How to test this

The new journeys cover the card in the pseudo-locale on both projects.
Run them from the repository root on either platform:

```
npx playwright test --project=journeys tests/e2e/journeys/i18n.spec.js -g "pull request card"
```

Both fail without this change. The Core journey walks every state #625
lists: signed out, "Not now" and "Show this again", the device code,
signed in with the form and its fold, a `rate-limited` failure, a dry
run, and a pull request opened from a checkout behind trunk. The
Gutenberg one walks signed out, signed in with the fold open, and the
opened pull request, checking the words that are Gutenberg's own.

What the journeys cannot reach is a real GitHub. They stub every
`github:*` handler, so the main-process errors never reach the screen in
them. Unit tests in `github-auth`, `github-pr` and `pr-stage` cover
those strings in the pseudo-locale instead. To see one on screen by hand
(either platform, current head):

1. From the repository root, run `npx electron . --lang=en-XA`.
2. Open a Core site with a linked ticket and an edit, and click **Review
& submit changes**.
3. In **Open a pull request**, click **Sign in with GitHub** and finish
in the browser.
- Expected: every line of the card is accented and in brackets, apart
from your login, your fork's name, the code and the branch.

**What must not have happened:** no English an English speaker sees has
changed. The English journeys in `open-pull-request.spec.js`,
`review-changes.spec.js` and `pr-checkout.spec.js` still pass with their
exact strings.

## Risks and limitations

- The other open batches (#636, #644, #645, #646) also append tests to
the end of `i18n.spec.js`, so whichever merges later resolves that by
keeping both.
- One finding is deferred: `prFailureMessage` decides between five
user-facing strings inside a `.jsx` file the suite cannot load. It
predates this PR (it was the old constant map), so moving it to a `.cjs`
module with a test is a follow-up.

<details>
<summary>Design decisions and alternatives considered</summary>

- **Not stacked on #635.** #622 asks for batches that review on their
own. Now that #635 has merged, its `unwrapped()` scanner change and the
`@wordpress/element` dependency, which this PR also needed, come from
trunk.
- **The textarea placeholder** is three strings joined with a newline. A
single `__()` with `\n` in it is refused by
`@wordpress/i18n-no-collapsible-whitespace`.
- **"Signed in as …"** is wrapped in its own `<span>`, so the sentence
and the **Sign out** button beside it are separate elements, as in #635.

2 [fix here] · 1 [follow-up]. Both [fix here] findings are fixed; the
follow-up is deferred (see Risks).

- 🟡 The Gutenberg journey linked no issue, so it never showed the form,
the fold or the loop-back. Fixed: it links one in the record and walks
those states.
- 🔵 No test showed the main-process strings or the stage labels come out
translated. Fixed: pseudo-locale unit tests for the scope refusal, a
composed `failure()`, the plural stale message and `prStageLabel`.
- Style: three dead entries in the journey's `THEIRS` filter were
removed.

- **Review:** completed. Fresh agent context, head `11ef362` / base
`c34aa45`. `npm run lint` clean, `npm test` 2002 pass / 0 fail, i18n and
PR journeys 25 pass.
- **Since review:** `11ef362 → ef457fd`. The only change is the test
fixes above, checked by the authoring session, not re-reviewed by a
fresh context. `src` and `tests` lint clean, unit suite 2005 pass / 0
fail, i18n journeys 12 pass. The review did not run the journeys itself;
it was read-only.
- **After #635 merged:** `ef457fd → 9559a1f` (trunk merged from GitHub)
→ `012fca8` (trunk at `e94f507` merged; `i18n.spec.js` resolved as
trunk's file plus this PR's two tests, nothing else changed). Checked by
the authoring session, not re-reviewed: `src` and `tests` lint clean,

## Why

The setup checklist and the trunk update's cards and banners were still
plain English in a translated app. This is the #626 batch of #622.

## What changes

- **Wrapped:** the setup checklist, the trunk update card, the question
an update asks over edits, the banners for an old trunk and an
incomplete update, the "Up to date with trunk" notice, and the sentences
they take from `setup-steps.cjs`, `update-plan.cjs`, `next-action.cjs`
and `project-type.cjs`'s `setup` copy. Also the dirty-tree dialog's
errors in `use-trunk-update.jsx` and the alert in `use-dev-server.jsx`.
- **Translated when shown, not at load:** `update-plan.cjs`'s messages
and step labels were module-level constants and are now functions
(`SKIP_INSTALL_MESSAGE` became `skipInstallMessage()`, and so on);
`project-type.cjs`'s `setup.*` are getters, like `description` already
was.
- **Whole sentences instead of parts:** the step counters
(`sprintf('step %1$d of %2$d')`), the file count and the day count
(`_n`), "Next step: %s", and the update summary, which was three
fragments and is now one of four sentences (`updateSummarySentence`).
The link-ticket hint took the work item's label as a noun ("Link a %s…")
and now takes its kind and has one sentence each, as #630 asks for.
- Commands and paths (`npm install`, `npm run build`, `package.json`,
`src/`) are passed in as `%s`.
- Deliberately not here: the lines the app writes to the Terminal belong
to #627, apart from the skip-install message, which #626 names because
the update card shows it too.

## How to test this

Covered by journeys in `tests/e2e/journeys/i18n.spec.js`, all red
without this change. From the repository root: `npx playwright test
--project=journeys tests/e2e/journeys/i18n.spec.js -g "checklist|trunk
banners|did not finish"`. In the en-XA pseudo-locale they reach the
checklist with steps done and ready, the checklist after a failed
install, the old-trunk banner, the question an update asks over an edit
(each answer chosen), the update card on its first step, and the banner
after an update that did not finish, and fail on any visible English.

To look at it by hand, on either platform, on the current head: run `npx
electron . --lang=en-XA` from the repository root and open a site whose
trunk is more than 14 days old.

1. **Expected:** the banner about the old trunk and its **Update to
latest trunk** button are accented and in brackets.
2. Edit a file in the site and click that button. **Expected:** the
dialog that asks what to do with the edit is bracketed throughout, apart
from the file's path.

**What must not have happened:** in English, the checklist, the cards
and the banners read exactly as before.

Not reached by a journey, and why:

- The setup chain's "Setting this site up for you — step N of M" and
"Setup stopped." notices: they only appear after a new site's clone,
which a journey would have to fake end to end.
- The "Up to date with trunk" notice: it needs an update to finish. Its
sentences come from `updateSummarySentence`, which a unit test covers.
- The alert about starting the server before the build: no control in
the app can reach it (the checklist's button is disabled until the build
is done, and the header and details only offer the server once the
wizard is skipped). It is wrapped anyway.

## Risks and limitations

- Review: 2 [fix here] · 0 [follow-up], both low, both fixed.
- `tray.spec.js`'s "the tray's edge is moved with the arrow keys…"
failed once in the full run. It fails about one run in five on `trunk`
too, so it is not this branch.
- The other open batches (#643, #644, #645, #646) also append tests to
the end of `tests/e2e/journeys/i18n.spec.js`, so whichever merges later
resolves that by keeping both.

<details>
<summary>Design decisions and alternatives considered</summary>

The dirty-tree answers' details carry their own leading dash ("— a .diff
on your machine…"), with the space outside the string: punctuation is
the translator's, and a string that starts with a space is easy to
break. The link-ticket hint takes `workItemNoun` instead of
`workItemLabel`, which removes one of the places #630 lists as splicing
the label into a sentence.

<summary>Review outcome (required, see AGENTS.md)</summary>

- **Review:** completed. Reviewer: a separate agent context (Claude

`.github/instructions/code-review.instructions.md`; head `1790e42` /
base `8dbed36`. `npm run lint` clean, `npm test` 1954 pass / 0 fail,

- Translatable-string rules [fix here]: the extractor gave the
dirty-tree details' notes to their labels as well, and gave the
dirty-tree errors' notes to the "Unknown error" fallback on the same
line. **Fixed** in `4b925eb`: each note sits directly above its own
string, and the fallback is on its own line.
- Tests [fix here]: nothing would fail if the new `update-plan.cjs`
message functions went back to English constants. **Fixed** in
`4b925eb`: a unit test loads a catalog after the module is required.
Checked by turning one back into a constant, which fails it.
- Notes on wording, also fixed: a stale comment in `work-item.cjs`, and
the translator example "2m 5s", which the app writes as "2m 05s".
  - It also confirmed the dev-server alert is unreachable from the UI.
- **Since review:** `1790e42 → 4b925eb` checked; the change is the fixes

- **After #635 merged:** `4b925eb → 7e0e1ad`, rebased onto trunk
`e94f507`. Only `tests/e2e/journeys/i18n.spec.js` conflicted: resolved
as trunk's file plus this PR's four tests, dropping this PR's copies of
the imports and `MY_EDIT`, which trunk now has. #635 brought the
identical `trunkDate` change to `git-site.cjs`, so it is no longer in
this diff. Checked by the authoring session, not re-reviewed: build and
lint clean, `npm test` 2035 pass / 0 fail / 2 skipped, the full journey

- The renamed `update-plan.cjs` exports have no consumer left under

change nothing there.

…h error (#647)

## Why

#630 is the last batch of #622. This PR is the part of it that doesn't
wait on the five open batches (#636, #643, #644, #645, #646): the mail
dialog, the Playground web server and the copy-path error were still
plain English, and `applyDoneMessage` spliced a verb and a noun into an
English sentence for any pair it had no sentence for.

## What changes

- The mail dialog: "From:", "To:", "CC:", "Date:", the Rendered and Raw
tabs, and the "Email" title of a mail with no subject.
- The Playground web server: its Start and Stop buttons, the loading
announcement, "Starting…", the panel's heading, "Stopped", and "Server
exited with code %d".
- The copy-path failure: the alert and the clipboard-unavailable message
in it.
- `applyDoneMessage`'s fallback is `_x('Done', 'an action that
finished')` instead of `` `${verb} the ${noun}` ``. No caller reaches it
today: the three in `use-apply-patch.jsx` pass only the five pairs it
has sentences for.

Not in this PR, because another open PR already wraps them or because
#630 says to wait for one:

| Item | Where |
|---|---|
| `COPY_BUTTON_LABELS` | #646 |
| "Dismiss" on the deep-link notice, "Choose application…" | #644 |
| "Setting up new site…" | #636 |
| `use-dev-server.jsx` leftovers | after #646 |
| `apply-card.cjs:191` period | after #645 |
| `project-type.cjs` `workItem.label` | after #643, #636, #644 |
| The full `--lang=en-XA` walk | after all five merge |

## How to test this

Two en-XA journeys cover this, and both are red without the change:

```bash
# from the repository root
npm run build:once
npx playwright test --project=journeys tests/e2e/journeys/i18n.spec.js -g "a mail the site sent|Playground web server"
```

- **a mail the site sent is fully translatable**: a mail on its Rendered
tab and its Raw tab, and a mail with no subject, whose dialog is titled
"Email".
- **the Playground web server is fully translatable**: stopped, starting
(including the live-region announcement), running, and after it exits
with code 1.

The English journeys in `mail.spec.js` still pass, so an English speaker
sees the same text as before.

What the journeys can't reach is the copy-path alert. It needs the
clipboard to refuse a write, and I couldn't stage that.

To look by hand (any platform, current head): run `npx electron .
--lang=en-XA` from the repository root, start a site's dev server, and
open a mail from the Email tray. Every label and both tabs show accented
and in brackets. The Playground web server only appears in a build that
ships `local-playground-web`, so a checkout won't show it.

**What must not have happened:** with no `--lang`, the mail dialog and
the web server read exactly as they did before.

## Risks and limitations

- Found while writing the web server journey: `@wordpress/a11y` adds a
screen-reader-only "Notifications" paragraph at DOM-ready, before the
app loads its locale, so it stays English. #630 doesn't list it, so it
isn't fixed here.
- The web server's other errors come from main (`'local-playground-web
directory not found.'`, or a thrown error) and stay English. That
belongs with the main-process strings, not this renderer batch.

head 4f8b808, base e94f507 (trunk). `npm run lint` clean, `npm test`
2033/2033.
- **Fixed:**
- The web server journey could pass with the loading announcement
unwrapped, because `speak()` writes outside the area scanned. It now
asserts `#a11y-speak-polite`.
- `__('Email')` only shows for a mail with no subject. The journey now
opens one.
- The `Done` fallback wasn't in the unit test that runs every sentence
through a catalog. It is now.
- A bare `__('Done')` would share a msgid with the `Done` button in
`@wordpress/components`. It now has a context.

Each new journey assertion was checked to fail with its string
unwrapped.
- **Deferred:**
- The mail journey excuses any text that is part of the mail. No label
is excused today, but matching whole text nodes would be stricter.
  - The web server's main-process error strings (see Risks).
- **Dropped:** the finding that "Dismiss", "Choose application…",
`COPY_BUTTON_LABELS` and "Setting up new site…" were unwrapped. The
reviewer read the issues, not the PR diffs; #644, #646 and #636 wrap
them.
- **Since review:** 4f8b808 → c9c5c0c, which contains only the fixes
above. Lint, unit tests and the i18n and mail journeys were rerun on
c9c5c0c.

…eaks left in wrapped code (#653)

## Why

#630 is the last batch of #622. #647 did the part that didn't depend on
the other batches. This does the rest, now that #636, #643, #644, #645
and #646 are merged: the en-XA sweep #630 asks for, and the two rule
breaks it named in already-wrapped code.

## What changes

**Found by the sweep:**
- xterm's own screen-reader strings: the terminal input's label
("Terminal input") and its "too much output" announcement, set through
`Terminal.strings` before each terminal is created.
- Main's refusal to submit while a patch is applied. It was `${label} is
applied. Revert it…`, a sentence spliced around the name, and it's shown
as-is in the patch pane. It's now two whole sentences, one with the name
and one without.
- The Playground web server's three errors from main (no folder to
serve, exits before it's ready, times out). #647's review deferred these
here.

**Rule breaks #630 named:**
- `apply-card.cjs` adds a full stop to a headline that lacks one. #630
said to drop it once main's errors carried their own. They don't, and
can't all: `patch-apply.js` messages double as terminal bullets, the
fallback headline is Git's own stderr line, and four paths pass a thrown
error's text. So the full stop stays but goes through `_x('%s.', …)` for
the translator to choose, and a sentence already ended in any script's
mark (`\p{Sentence_Terminal}`) keeps it.
- `workItem.label` is removed from both project types. Nothing read it
once the sentences that named a work item became one per kind.

**Already done, nothing to change:** `use-dev-server.jsx` had nothing
left after #646.

## How to test this

Any platform, current head. The suites cover it:

```bash
# from the repository root
npm test
npm run build:once
npx playwright test --project=journeys tests/e2e/journeys/i18n.spec.js
```

- `ipc-wiring.test.cjs` has two new pseudo-locale tests, for main's
refusal (with and without a name) and the web server's failures. Both
are red on the old `main.js`.
- `apply-card.test.cjs` checks the translated full stop, and that
sentences ended in `。`, `؟` and `।` keep their mark.
- The i18n Terminal journey now finds the input by its translated name.
The apply card journey now expects the whole refusal, full stop
included, as one translated string.

To look by hand: run `npx electron . --lang=en-XA` from the repository
root, open a site, open the Terminal tray, and inspect the terminal's
textarea. Its `aria-label` is bracketed and accented.

**What must not have happened:** with no `--lang`, nothing reads
differently. The refusal, the web server errors and the terminal's label
are the same English as before, and `mail.spec.js`, `terminal.spec.js`
and the rest of the English journeys pass unchanged.

## Risks and limitations

- **What the sweep covered:** I launched en-XA with a Core site and a
Gutenberg site, opened every tray, log tab and settings tab, the site
menu and the create dialog, and scanned the whole window. After the
xterm fix, the only English left was product names, commands, the `$`
prompt and PHP version numbers. It didn't open every dialog or failure
state; the existing i18n journeys cover many of those.
- **Left on purpose** (#622's do-not-wrap list): main's argument guards
(`'Site is not registered'`, `'No running script'`), the `github-prs.js`
and `trac-view.js` errors that are replaced by a status before display,
and `console.error` messages.
- **Untested:** `'Timed out starting web server'` is wrapped but has no
test. It needs fake timers for its 20-second wait.
- #648 (the a11y "Notifications" text) is separate.

<summary>Review outcome</summary>

**1 [fix here] · 1 [follow-up]. The fix is applied in c2eb4ba.**

- **Review:** completed by a separate agent with a fresh context,
against `.github/instructions/code-review.instructions.md`. Reviewed
head c53312a, base 8303849 (trunk). `npm run lint` clean, `npm test`
2081/2081, full journey suite 147/147 on c53312a.
- **Fixed:** the list of marks that end a sentence missed Devanagari
`।`, Armenian, Ethiopic, Khmer and Myanmar, so a Hindi sentence would
have got a second mark. It now uses `\p{Sentence_Terminal}`, with a
Hindi case in the test. The doc comment's over-long line was rewrapped.
- **Deferred:** a test for the web server's 20-second timeout (see
Risks).
- **Confirmed by the review:**
- xterm reads `promptLabel` in `open()` and `tooMuchOutput` on each
announcement, so setting both before `new Terminal` is early enough.
- The refusal's English is unchanged for every label, including a blank
one.
  - Nothing reads `workItem.label`.
  - No English journey asserts a changed string.
- **Since review:** c53312a → c2eb4ba, which contains only the fix
above. Lint, unit tests (2081) and the i18n journeys were rerun on
c2eb4ba. One i18n journey (site details and menu, which this branch
doesn't touch) failed once in that run, then passed three times on its
own and in the full run before. That's a flake.
