* fix(setup): resolve the configuration MSIX Claude Desktop reads
On Windows, setup, doctor and uninstall always used
%APPDATA%\Claude\claude_desktop_config.json. The MSIX build of Claude
Desktop (package family Claude_pzs8sxrjxfjjc) virtualizes AppData writes
and reads its package-private copy under
%LOCALAPPDATA%\Packages\<family>\LocalCache\Roaming\Claude once it exists.
Setup from an ordinary process therefore wrote a file the app never reads,
and doctor reported that file healthy.
Resolve the Claude Desktop location once, in supportedClients(): the
private copy when it exists, else the AppData file the package still
reads, else a new private copy. An unrecognized Claude_* publisher or
unreadable package storage is reported instead of falling back to AppData.
Compare one of the package's private files with its AppData path through
realpath.native to learn whether the running package started this
process. From that redirected view, or when no file can be compared,
setup and uninstall refuse to change Claude Desktop's configuration,
because the running app rewrites it from memory. From a redirected view
they also refuse writes under %APPDATA% and %LOCALAPPDATA% for other
clients and skills, which would land in the package's private storage.
Setup refuses to register a launcher stored in any MSIX package's
private storage, discloses which file the package reads, and tells the
user to quit Claude Desktop fully on every platform. Configuration fails
with target_changed if the package switched to its private copy after
the plan was shown. Uninstall removes REA from both files.

* docs(setup): record the verified MSIX Claude Desktop registration
On the Windows 11 host with the MSIX build 2.31226.1.0, setup from an
ordinary terminal with the app quit wrote the package-private copy. After
the app restarted, the entry persisted, doctor reported it aligned, and
Claude Desktop's MCP log showed REA starting and answering tools/list.
Uninstall against the real app remains unverified.

* style(setup): format MSIX review corrections
* fix(setup): carry the admitted legacy path through uninstall removal
clientRegistrationRemoval returned a removeLegacy boolean, and removeClient
recomputed the legacy path separately, so TypeScript could not prove the
path existed when removeLegacy was true and `tsc --noEmit` failed in
Uninstall.ts. The decision now returns the admitted legacy path itself;
preflight and removal consume that one value.
The alias regression matched new-destination children with a "/"
separator while building paths with path.join, so it failed on Windows.
It now uses path.sep.

* test(setup): split MSIX Claude Desktop lifecycle cases under the function length limit
The uninstall cases pushed the registration lifecycle describe past the 150-line lint limit. Group them separately, with the AppData registration case kept among the registration cases.
