* fix(server): back off degraded git polling on an unchanged workspace
When the recursive watcher declines a repository (over 250,000 entries on
macOS/Windows, or any watcher setup failure), WorkspaceGit falls back to
polling. That fallback rescheduled itself every 5 seconds for as long as the
workspace existed, with no client or agent involved. On a repository large
enough to defeat the watcher each tick is an expensive `git status`, so the
daemon held about a core indefinitely.
Double the gap after every tick whose workspace snapshot came back identical,
up to a 60-second ceiling, and reset to the 5-second base on the first change.
Both degraded loops — working tree and repository metadata — share the rule.
Explicit reads still force a refresh, so the ceiling only bounds how long an
edit made outside Paseo stays undiscovered.
Fixes#5102
* test(server): cover repository-metadata degraded backoff, document failed-tick semantics
* test(server): drive the recovery-refresh assertion off the fake clock, not waitFor
* test(server): declare metadata poll counter as a function
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.
