Recover daemon workers stalled by workspace Git pressure (#3033)

* fix(server): bound workspace git pipelines

* fix(server): bound workspace git watcher setup

* fix(server): recover unresponsive daemon workers

* fix(server): tolerate transient daemon heartbeat delays

A five-second watchdog threshold can replace a healthy worker during a short event-loop delay. Keep recovery bounded while allowing a 15-second heartbeat gap, and preserve process-level coverage for workers that ignore graceful termination.

* test(server): normalize workspace fixture paths

Workspace Git entry points resolve paths before invoking dependencies. Keep admission-control fixtures keyed by the same canonical paths so their assertions and deferred gates work on Windows.
