## What changed - Add `GetProcessMetrics` and provider sampling APIs for process ID, start time, cumulative CPU time, and resident memory, exposed through `ThreadManager` without creating a thread or session. - Distinguish unsupported collection, a locally absent host, and sampling failures. Process-owned providers never start or replace a host when sampling. - Bound gRPC sampling to one second without retries or explicit connection resets. Run optional collectors on a detached worker with at most one collection in flight, so stalled collection cannot block the HTTP/2 driver or runtime shutdown. ## Testing Add coverage for snapshots, collector errors and panics, deadlines, overload, and shutdown with a stuck collector. Extend lifecycle tests to check that sampling preserves session state and keepalive behavior without starting or restarting local hosts. GitOrigin-RevId: eeafe275891d0464636f28a29345a87aed1a12dc
