- Actor: use lifecycle::cancel() instead of handle.cancel() on channel
close and Abort, ensuring end-stream frame is always emitted
- Lifecycle: use match instead of ? on encode_error_end_stream with
fallback end-stream frame to prevent silent hangs
- Dispatch: add Bash tool alias for Shell
- Context/Blob sync: increase timeouts from 15s to 60s
- Providers: add detailed debug logging to openai_chat and router
