concurrency: Add support for queue key - #654

gh-aw v0.76.1 emits `concurrency.queue` in compiled `*.lock.yml`
workflows, but actionlint v1.7.12 (latest) does not yet recognize
the key. Add a scoped ignore pattern under the existing
`.github/workflows/*.lock.yml` paths block so YAML lint passes
on PRs that include recompiled lock files.

Remove the pattern once rhysd/actionlint#654 lands.

actionlint v1.7.11 does not yet recognize the queue key in
concurrency sections. Add .github/actionlint.yml to ignore this
specific error until rhysd/actionlint#654 is merged and released.

Add queue: max to the docs-deploy concurrency group so that
pending runs are queued rather than skipped.

## What

PR-A1 of the approved claude-review-lanes plan
(`docs/topics/claude-review-lanes/PLAN.md`, committed here) —
structural, behavior-preserving:

- **Three composite actions** extracted from the review lanes' embedded
steps, unreferenced until PR-A2 repoints the reusables at this PR's
merge SHA (self-reference pins resolve only post-merge):
- `claude-lane-freshness` — live superseded-head guard (github-script).
- `claude-lane-outcome` — outcome reporter with the infra-failure
classifier rewritten from the generated bash/jq embed into
`classify.cjs` on the github-script runtime (resolves the plan's F7: no
more jq/runner-tool dependency). Full 23-case shell corpus ported to
`node --test` (`classify.test.cjs`, co-located; wired into ci.yml).
- `claude-lane-marker-comment` — marker-comment lifecycle (upsert on
failure / clear on success), owning the fork-PR guard; lane strings are
inputs.
- **`.github/actionlint.yaml`** — pre-approved suppression for
actionlint 1.7.12's rejection of the GA `concurrency.queue` key
(rhysd/actionlint#654), scoped to that one syntax-check message, with
removal trigger. Probe evidence in PLAN.md Phase 0.
- **PLAN.md** — plan artifact + Phase 0 probe results (queue
serialization on all three shapes, ready_for_review draft payload,
kill-switch skip conclusions).

The four generated-embed classifier files (`classify-infra-failure.*`,
`render-classify-infra-failure.*`) retire in PR-A2 with the embed
replacement — the render tripwire still guards the live embeds until
then.

No linked issue (the plan's issue sweep closes #150/#158/#227/#242 at
Phase 3f).

## Related

- `docs/topics/claude-review-lanes/PLAN.md` — the approved plan; this is
Phase 2 PR-A1.
- melodic-software/standards#278 — Phase 1 (REVIEW.md lane scoping),
merged separately.
- rhysd/actionlint#654 — upstream gap behind the actionlint suppression.

## Verification

- `node --test .github/actions/claude-lane-outcome/*.test.cjs` — 10/10
pass (ported corpus).
- `node --test .github/scripts/*.test.cjs` — 273 pass; `bash
.github/scripts/classify-infra-failure.test.sh` still green (untouched
here).
- zizmor on all three new action files — no findings.
- actionlint 1.7.12 with the new config: queue suppression verified
empirically (exit 0 with config, exit 1 without).

ci-workflows is a manifest target carrying its own .github/actionlint.yaml
— the canonical origin this component's content mirrors — yet had no
actionlint classification, which the ownership model reads as "not
classified". Marks it locally-owned so the most relevant repo is
deliberately classified; the removal trigger on rhysd/actionlint#654
fires there too.

Plan output for ci-workflows confirms no materialization:
"locally-owned actionlint (not modified)".
