+Handle fs.watch close without spurious restarts; add tests and improve test runner
+
+- Prevent spurious restarts and noisy warnings on fs.watch 'close' by checking the internal isWatching flag before logging and restarting (ts/watchers/watcher.node.ts).
+- Add comprehensive test suites covering basic operations, inode-change detection, atomic writes and stress scenarios (test/test.basic.ts, test/test.inode.ts, test/test.stress.ts).
+- Remove outdated test (test/test.ts) and delete the test asset test/assets/hi.txt.
+- Update test script in package.json to enable verbose logging, write a logfile and increase timeout to 120s to reduce flakiness in test runs.
+
 ## 2025-12-10 - 6.2.0 - feat(watchers)
 Improve Node watcher robustness: file-level inode tracking, abortable restarts, restart race guards, and untracked-file handling
