feat(crossplatform): add Python 3 ports for all 58 PS1 skill scripts

Add cross-platform Python alternatives alongside existing PowerShell
scripts. PS1 remains the default runtime; Python is opt-in via switch
scripts. All parameters are identical between runtimes.

New files:
- 58 Python scripts in .claude/skills/*/scripts/*.py
- scripts/switch-to-python.py and switch-to-powershell.py
- docs/python-porting-guide.md
- __pycache__/ added to .gitignore
