Auto-commit: Fix spinning logs — API timeouts + reliable Huey consumer start

Root causes of indefinite spinning during book create/generate:

1. ai/models.py — ResilientModel.generate_content() had no timeout: a
   stalled Gemini API call would block the thread forever. Now injects
   request_options={"timeout": 180} into every call. Also removed the
   dangerous init_models(force=True) call inside the retry handler, which
   was making a second network call during an existing API failure.

2. ai/setup.py — genai.list_models() calls in get_optimal_model(),
   select_best_models(), and init_models() had no timeout. Added
   request_options={"timeout": 30} to all three calls so model init
   fails fast rather than hanging indefinitely.

3. web/app.py — Huey task consumer only started inside
   `if __name__ == "__main__":`, meaning tasks queued via flask run,
   gunicorn, or other WSGI runners were never executed (status stuck at
   "queued" forever). Moved consumer start to module level with a
   WERKZEUG_RUN_MAIN guard to prevent double-start under the reloader.
