Adam Moussa 15a52bff40 Add background auto-review worker with SQLite cache ... Pre-compute PR reviews so they are ready the moment a PR is opened in the queue, instead of waiting on an on-demand Fireworks call each time. A daemon worker polls the queue every POLL_INTERVAL and reviews new or changed non-draft PRs into a local SQLite cache (gitignored). Change detection is two-level: skip when the PR's updated_at is unchanged, and even when it moved, skip the model call when the diff's SHA-256 matches, so comment-only bumps do not burn tokens. Failed reviews retry up to MAX_REVIEW_ATTEMPTS with 429 backoff; departed PRs are closed with a grace window before purge. Singletons are initialized eagerly in the FastAPI lifespan before the worker thread starts to avoid an init race; all cache writes are serialized. New endpoints GET /api/reviews and POST /api/refresh back a dashboard that polls for status (reviewing/ready/error) and opens a ready review instantly. Nothing is posted automatically; the human still decides. Stdlib-only, so no new runtime or test dependencies.		2026-07-01 14:28:11 -04:00
