Module error 

Agent run error — carries the provider error AND the agent’s exported conversation state so the recovery coordinator can snapshot→restore rather than re-fork from scratch (RFC-029 §3.2, P2b).

Used by run_agent on failure: before returning Err, the agent’s export_state() is captured and wrapped. The supervisor’s Err arm downcasts back to extract both the source error (for classify) and the restore state (for ExecutionResult.restore_state).
