A session_reset (/new, /cc) that bumps the run generation while an agent turn is in flight left the dead agent in the _running_agents slot: the in-flight run's own release is generation-guarded and correctly returns False, and the outer finally's sentinel-only check also missed the leftover real agent. The session then silently dropped every subsequent message as 'agent busy' until a full gateway restart. (#28686) - _process_message_or_command outer finally now calls the unconditional, idempotent _release_running_agent_state(key) on all exit paths instead of the sentinel-vs-else branch that could strand a dead agent. - _handle_reset_command evicts the slot right after bumping the generation, so the zombie is cleared at reset time regardless of how the in-flight run unwinds.
