docs: Fix Phase 3 status - partially complete

Phase 3 is NOT fully complete:
- ✅ All paths finding IS implemented (toPaths, allPaths, paths)
- ❌ Pattern matching NOT implemented
- ❌ Bulk operations NOT implemented

Changed status from 'Complete ✅' to 'Partial ✅' to reflect reality.
Deferred pattern matching and bulk ops to post-v1.0 polish phase.
