Remove AI watermarks

Drive the remove-ai-watermarks CLI. Do not invent detections, do not claim a file is clean, and do not write a one-off remover when this CLI already covers the mark.

This skill must work in any coding harness and with weaker models. Follow the checklist. Trust scripts/probe.py over guesses about GPU, Python, or installers.
