Claude Code: Add WORKER_MODE=auto to .env.example for guaranteed agent startup

The entrypoint.sh regenerates .env from .env.example on container startup.
Previously, WORKER_MODE was not set, causing the worker to potentially not start.
Now explicitly setting WORKER_MODE=auto ensures the agent loop is enabled.
