Claude Code: Add missing AGENT_MODE and WORKER_START_TIMEOUT to .env

- Add AGENT_MODE=active to .env.example (prevents brain from defaulting to sleep)
- Add WORKER_START_TIMEOUT=30 to .env.example (prevents crash loop)
- Update env_init.py critical defaults to include new variables

These variables were missing and causing the Brain to stay in IDLE state
instead of transitioning to RUNNING/active processing.
