Release: Targeted Cache Invalidation

This release improves responsiveness by invalidating attribute cache entries only for affected files/paths, instead of clearing broad cache state.

What changed

Added path-based cache invalidation on vault events:
- modify → invalidate changed file path
- delete → invalidate removed file path
- rename → invalidate both old and new paths
- folder-rename safety via prefix invalidation
Added throttled visible refresh after invalidation to keep UI updates smooth
