Update .gitignore with comprehensive Python project patterns

Enhanced .gitignore with:
- Complete Python packaging patterns (pip, poetry, pipenv)
- Testing and coverage tools (pytest, tox, coverage)
- Virtual environment patterns (.venv, env, etc)
- Modern IDE support (VS Code, PyCharm, Sublime)
- Security patterns (.env files, certificates, keys)
- Build artifacts (wheels, distributions, installers)
- Documentation builds (Sphinx, MkDocs)
- SuperClaude-specific patterns (.serena, .superclaude)

Organized in logical sections for better maintainability.
