⚡ Bolt: [performance improvement] Disable synchronous stdout logging in YOLO inference

[kingkillery]

💡 What:
Added verbose=False to model.predict() calls in commonforms/inference.py.

🎯 Why:
By default, Ultralytics YOLO models log inference details (e.g., image size, bounding box coordinates, timings) to standard output for every single prediction. Synchronous logging to stdout creates blocking I/O overhead that accumulates, particularly when processing sequences of inputs (like document pages) inside loops.

📊 Impact:
Eliminates blocking I/O overhead during document processing, marginally speeding up throughput when predicting across multiple pages or running the CLI on large PDFs.

🔬 Measurement:
Run uv run pytest tests/inference_test.py to confirm the form extraction is completely unaffected and verify that extraneous stdout logging from the model no longer occurs.

Walkthrough

This update disables synchronous verbose logging in YOLO inference calls by setting verbose=False on prediction methods. A learning note documents this optimization technique to reduce I/O blocking overhead during repeated predictions.

Changes

Cohort / File(s)	Summary
YOLO Verbose Logging Configuration .jules/bolt.md	New documentation file with learning note recommending verbose=False parameter in YOLO inference calls to eliminate stdout logging I/O overhead.
Inference Implementation commonforms/inference.py	Updated YOLO.predict() calls in FFDNetDetector.extract_widgets to include verbose=False parameter on both ONNX and PyTorch prediction paths.

Poem

🐰 A speedy prediction we seek,
When verbose chatter makes logging weak,
False be the flag, and silent the call,
No blocking I/O—we inference them all!
