Claude Code: Fix health_monitor import paths and brain initialization

- Fix sys.path setup to use openclaw package import first
- Fix check_brain_health to use proper 'from agents import brain_minimal'
- Fix check_rbac_health to use proper 'from agents import rbac'
- Specify agent_name='cain' in get_brain() call
