feat: search project files from Quick Open

[wolfiesch]

Summary

• add a strict, negotiated files.search command using the existing files.list permission
• resolve the active project root through OMP, then run a bounded Git-aware or directory fallback scan in the T4 host
• merge debounced project matches into Quick Open while preserving honest loaded-file fallback states
• document the ownership, privacy, symlink, timeout, and result-limit boundaries

Verification

• bun run check
• bun run test
• bun run test:tooling
• bunx playwright test e2e/remote-app.spec.ts --grep "shows verified session context|finds loaded files"
• git diff --check

The UI change is search wiring and compact status copy; screenshots would not add meaningful evidence beyond the focused browser interaction test.
