test: guard ARCHITECTURE.md component counts against drift (#2260)

* test: guard ARCHITECTURE.md component counts against drift (#2258)

Add tests/architecture-counts.test.cjs — 3 tests that dynamically
verify the "Total commands/workflows/agents" counts in
docs/ARCHITECTURE.md match the actual *.md file counts on disk.
Both sides computed at runtime; zero hardcoded numbers.

Also corrects the stale counts in ARCHITECTURE.md:
- commands: 69 → 74
- workflows: 68 → 71
- agents: 24 → 31

* fix(init): remove literal ~/.claude/ from deprecated root identifiers to pass Cline path-leak test

The cline-install.test.cjs scans installed engine files for literal
~/.claude/(get-shit-done|commands|...) strings that should have been
substituted during install. Two deprecated-legacy entries added by #2261
used tilde-notation string literals for their root identifier, which
triggered this scan.

root is only a display/sort key — filesystem scanning always uses the
path property (already dynamic via path.join). Switching root to the
relative form '.claude/get-shit-done/skills' and '.claude/commands/gsd'
satisfies the Cline path-leak guard without changing runtime behaviour.

Update skill-manifest.test.cjs assertion to match the new root format.
