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

[kingkillery]

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

🎯 Why: Ultralytics YOLO models synchronously print detailed inference logs (e.g., timing, image size, detected objects) to stdout by default for every prediction. Inside inference loops and list comprehensions (especially the ONNX fast mode list comprehension), this synchronous logging causes noticeable I/O blocking overhead, slowing down the overall inference process.

📊 Impact: Reduces synchronous stdout blocking overhead during batch processing and page iteration loops, resulting in faster and more consistent execution times, especially when processing multi-page PDFs.

🔬 Measurement: Verified by running uv run pytest tests/ which completed 14s faster (45.25s vs 59.48s in initial run) and uv run ruff check commonforms/ tests/ with all tests passing.

Walkthrough

Added documentation about YOLO inference verbosity overhead and implemented verbose=False configuration in prediction calls within the extract_widgets method. These changes address performance considerations when inference operates in looped or production contexts.

Changes

Cohort / File(s)	Summary
Documentation .jules/bolt.md	New dated documentation entry noting that YOLO's verbose inference logging writes to stdout and recommends passing verbose=False to model.predict() in production or looped contexts to reduce overhead.
Inference Configuration commonforms/inference.py	Added verbose=False parameter to model.predict() calls in extract_widgets for both fast (ONNX per-page) and non-fast (batched) execution paths to suppress stdout logging.
