- Added native `FileLock` bindings supporting cross-process advisory locking on Linux, Unix, and Windows. - Replaced directory-based file locking and custom stale-lock reclamation with OS-backed native locks. - Updated TypeScript declarations, native bindings, and package documentation for the new API. - Added comprehensive unit tests and fixtures validating single-owner constraints and process death handoff.
