Renames the two outlier spaced directories in lockstep across the
signed top-level tree and the unsigned src/ tree:

    Windows Dev Config/      -> windows-dev-config/
    Wsl Comfort/             -> wsl-comfort/
    src/Windows Dev Config/  -> src/windows-dev-config/
    src/Wsl Comfort/         -> src/wsl-comfort/

The sibling Workloads/<lang>/ directories already use kebab/lowercase
(dotnet/, winforms/, etc.); this aligns the two outliers with that
convention. The friendly product names "Windows Dev Config" and "WSL
Comfort" remain in section headings and prose - only the four parent
directory names change. Filenames inside those directories
(dev-config.winget, install.ps1, README.md, readme.md,
comfort-shell-bootstrap.sh) are unchanged.

Why
---

Every documented command and cross-link in the repo had to defend
against the space:

    winget configure -f ".\Windows Dev Config\dev-config.winget" `
        --accept-configuration-agreements --disable-interactivity

    & ".\Wsl Comfort\install.ps1"

That second example needs the `&` call operator only because the path
is a quoted string literal - `.\Wsl Comfort\install.ps1` without quotes
is a PowerShell syntax error, and `& .\Wsl Comfort\install.ps1` (no
surrounding quotes) calls `.\Wsl` with `Comfort\install.ps1` as an
argument. Tab completion auto-quotes the path
(`.\"Windows Dev Config"\`), producing a different syntactic shape
than what the docs show. Every markdown cross-link had to URL-encode
the space (`%20`). None of these affect the sibling Workloads/<lang>/
flows, because none of those have a space.

Post-rename the same commands are:

    winget configure -f .\windows-dev-config\dev-config.winget `
        --accept-configuration-agreements --disable-interactivity

    .\wsl-comfort\install.ps1

No quoting, no `&`, no `%20`.

What changed
------------

* git mv across the four directories. File blobs are unchanged; the
  signed top-level install.ps1's still carry their Authenticode
  signature block (`# SIG # Begin signature block` ... `# SIG # End
  signature block`), the src/ copies remain unsigned. Verified
  on-disk after the rename.
* README.md: five command/link references updated; the WSL Comfort
  invocation simplifies from `& ".\Wsl Comfort\install.ps1"` to
  `.\wsl-comfort\install.ps1`.
* src/docs/development.md: two table links and two repo-layout-tree
  lines.
* src/manifest.yml: `install` and `configuration` paths for the
  manual-test flows (`comfort-shell`, `calm-os`). The pre-existing
  asymmetry where these two flows declare paths without a `src/`
  prefix (the automated workloads use `src/Workloads/...`) is
  preserved - that is a separate cleanup not in scope here.
* .pipelines/OneBranch.SignAndPackage.yml: the CopyFiles@2 `Contents`
  glob lines for the signed release artifact.
* No script or .cs file inside the moved directories references its
  parent dir by name. PowerShell scripts use $PSScriptRoot;
  comfort-shell-bootstrap.sh is self-relative. Verified by grep.

Inside the repo nothing else mentions the old names as a path. The
only remaining instances of the strings "Windows Dev Config" and "WSL
Comfort" are in human prose - the README's section heading, the
feature description paragraphs, and a Troubleshooting bullet that
names the product, not the path.

External impact (out of scope of the patch, called out for awareness)
---------------------------------------------------------------------

GitHub does not provide URL redirects for renamed paths. Any bookmark,
blog post, Slack/Teams link, or wiki page pointing at
github.com/microsoft/WindowsDeveloperConfig/.../Windows%20Dev%20Config/
or .../Wsl%20Comfort/ will start returning 404 once this merges. The
proposal weighed leaving a single-file MOVED.md placeholder at each
old path; the placeholder approach was rejected because it would
re-introduce the spaced directory names just to host a redirect note,
defeating the goal of the rename and re-creating the tab-completion
ambiguity. The mitigation is a release announcement and a heads-up to
any in-repo PR authors to rebase.

Verification
------------

* Re-ran the same static markdown link scan that was used to find the
  five broken links fixed in #7: 0 broken out of 182 links on the
  renamed tree.
* grep on the working tree for the patterns `Windows Dev Config/`,
  `Wsl Comfort/`, `Windows%20Dev%20Config`, `Wsl%20Comfort`,
  `".\Windows Dev Config`, `".\Wsl Comfort` returns no matches.
* git diff --stat confirms 16 files changed, 14 insertions(+), 14
  deletions(-) - all inside the four manifest+docs+pipeline files
  above. Body bytes of the moved scripts are unchanged.
