god: Fix alive field - don't let /api/state override HF API stage

- action_check_health() and init_child_state() were incorrectly setting
alive=True and stage=RUNNING when /api/state endpoint responded
- This masked RUNTIME_ERROR state because the container still responds
on /api/state even when app has crashed
- HF API space_info().runtime.stage is the source of truth for stage/alive
- Health check should only return status string, not modify state
