## Why
The Windows `notify` backend wakes every 100 ms even when idle.
## What changed
- Patch `notify` 8.2.0 in Bazel to wait indefinitely for events or control requests.
- Wake the watcher when configuration requests are queued and share ownership of the wakeup semaphore with `Arc<OwnedHandle>`.
## Testing
Add a Windows regression test that verifies file changes are reported after unregistering one directory and registering another on the same watcher.
