fix: use uv directly in pre-commit hooks for cross-platform support

Fixes #4322

The previous pre-commit config used bash-specific commands that don't work
on Windows:
- bash -c '...' wrapper
- source command
- Unix-style paths (.venv/bin/activate)

This change simplifies the entry commands to use 'uv run' directly, which:
- Works on Windows, Linux, and macOS
- Automatically handles virtual environment activation
- Removes the need for bash-specific syntax
