[BUG] skill-creator: scripts fail on Windows when Python is managed by uv

What's Wrong?

generate_review.py and run_loop.py are invoked with bare python or python3. On Windows with uv, these are Store stubs that print an error and exit immediately.

What Should Happen?

The scripts should detect the available Python binary at runtime: try uv run python first, then python3, then python.

Error Messages/Logs

Steps to Reproduce

1. Install Claude Code on Windows with Python managed by uv (no standalone python in PATH)
2. Create a skill with skill-creator
3. At the eval step, Claude invokes python generate_review.py ...
4. Error: Python est introuvable ; executez sans arguments a installer depuis le Microsoft Store
