MAESTRO: fix(cursor): use bun runtime and fix hooks directory detection

Browse Source 
Cherry-picked source changes from PR #721. Fixes two Cursor standalone
setup bugs:

1. findCursorHooksDir() now checks for hooks.json (unified CLI mode)
   in addition to legacy common.sh/common.ps1 scripts
2. installCursorHooks() now uses bun instead of node for hook commands
   since worker-service.cjs depends on bun:sqlite
3. Added findBunPath() to detect bun executable across platforms

Build artifacts skipped (pre-existing dompurify viewer dep issue).
Source-only cherry-pick, TypeScript compilation clean for modified file.
