Refresh Git exclusions when ignored directories appear after subscription and bound Linux and native classification work. Preserve tracked-file notifications, ignore-update barriers, and watcher recovery.
Fixes#4558. Supersedes #4808 by @Marcus172; this change incorporates six commits originally authored by Marek Rom and adds verified follow-up fixes. The independent session-context leak is fixed by #5208. Combined isolated daemon verification passed.

* fix(server): trust healthy workspace git watchers
Quiet observed workspaces were periodically scheduling full Git refreshes, saturating the daemon-wide process pool as workspace count grew. Keep only cheap observation re-ensure work, refresh ignore paths from watcher events, and detect silent metadata watchers with a one-shot canary before accepting the subscription.
* fix(server): refresh watcher ignores from git metadata
Repository exclude and Git configuration changes also affect the standard ignore set. Route those metadata events back to linked working-tree observations so their excluded directory lists stay current without periodic Git polling.
* test(server): drive ignore updates through watcher events
The integration contract now exercises the production event-driven ignore refresh instead of waiting for the removed periodic audit.
* fix(server): normalize git metadata paths on windows
File observation returns platform-native relative separators. Normalize those paths before matching Git metadata names so repository exclusion changes refresh working-tree ignores on Windows too.
* fix(server): trail concurrent ignore refreshes
Remember ignore-source events that arrive during an in-flight Git query and recompute once more before considering the working-tree observer current.
