CRF-40: ensure runDoneCh is closed even if NewWatcher fails so Close does not deadlock waiting on a goroutine that already exited. CRF-41: gate snapshot publishes with a monotonic resolveEpoch counter. Resync and resolveAndBroadcast drop m.mu around the filesystem walk; under concurrency a stale walk could overwrite a fresher one at a higher version number. Each pass now captures its epoch under the lock and skips the publish if a newer pass has started. Resync returns the currently published Snapshot in the stale case, which is guaranteed to be at least as fresh as the discarded result. CRF-42: hash the (capped) prefix of oversize SKILL.md files so an edit that keeps the file oversize still shifts the aggregate hash, matching readFileResource and preserving the change-detection contract.
