fix: normalize Windows paths in update scope detection (#2278)

* docs: sync ARCHITECTURE.md command count to 74

commands/gsd/ has 74 .md files; the two count references in
ARCHITECTURE.md still said 73. Fixes the command-count-sync
regression test.

* fix: normalize Windows paths in update scope detection (#2232)

On Windows with Git Bash, `pwd` returns POSIX-style /c/Users/... paths
while execution_context carries Windows-style C:/Users/... paths. The
string equality check for LOCAL vs GLOBAL install scope never matched,
so every local install on Windows was misdetected as GLOBAL and the
wrong (global) install was updated.

Fix: normalize both paths to POSIX drive-letter form before comparing,
using portable POSIX shell (case+printf+tr, no GNU extensions).

Closes #2232

* feat(commands): add gsd:inbox command for GitHub issue/PR triage

inbox.md was created but not committed, causing the command count
to read 73 in git while ARCHITECTURE.md correctly stated 74.
