Computer-vision failure detection worker for the Continuum print farm platform. Consumes camera frame batches pushed onto the Redis Stream stream:camera_frames (by continuum-backend's src/queue/), runs them through an ONNX Runtime model, and fast-paths high-confidence failure alerts back to Redis and Postgres.
