docs: add quality and maintenance badges to README files (#88)

Add comprehensive badge set to both README.md and README.rst to signal
project quality, maintenance status, and community standards.

Badges added:
- Build Status: CI/CD pipeline status from GitHub Actions
- PyPI Version: Latest package version on PyPI
- Python Versions: Supported Python versions (3.9-3.12, PyPy)
- License: MIT license badge
- Ruff: Modern Python linter for code quality
- Maintained: Active development indicator

Badges preserved from original README.rst:
- Documentation Status: ReadTheDocs build status
- Coverage: Code coverage from codecov

These badges help users quickly assess:
- Project stability and CI health
- Package availability and compatibility
- Code quality standards
- Active maintenance and support
