Linear Rate-Limit Freeze Fixes

A cluster of fixes targeting the shared Linear bucket saturation that was freezing fleet dispatch and silently stalling replicas. Fence-guard reads are now cached (45s TTL), anchor UUID lookups are cached permanently, and dispatch reads route through the replica instead of hitting Linear live — together dropping breaker trips from ~18 per 3 minutes to near zero. A cloud-sync stall watchdog now detects frozen replica sockets and self-heals via process restart rather than sitting silent for hours, and interactive claude sessions now load plugins from ~/catalyst/plugin-source on the same path as workers.
