Claude Code: Confirm health fixes - treat null/unknown error as healthy

- Bump openclaw version to 0.1.1
- Add diagnostic note to status file (error=null = healthy)
- Force Space rebuild to ensure latest health_monitor fixes are deployed

The health_monitor.py now correctly treats:
- null error field as healthy (no error)
- "unknown" error as healthy (no specific error occurred)
- Only treats actual error strings as errors
