✨ feat(logger): improve logging docstrings for clarity

- update `setup_logging` to include detailed docstring explaining usage and fallback behavior
- enhance `get_logger` docstring with clear args and return details

🔥 chore: remove IntelliJ project file from version control

- delete `.idea/pedros.iml` to avoid tracking editor-specific configuration

📝 docs(readme): update PyPI badge link in README

- switch badge and link to new package name `pedros`
- tweak license description for consistency
