Update tests for new Process model-based architecture
- Remove pid_utils tests (module deleted in dev) - Update orchestrator tests to use Process model for tracking - Add tests for Process.current(), cleanup_stale_running(), terminate() - Add tests for Process hierarchy (parent/child, root, depth) - Add tests for Process.get_running(), get_running_count() - Add tests for ProcessMachine state machine - Update machine model tests to match current API (from_jsonl vs from_json)
