feat: Add professional badges and fix badge lightbox issue

Added professional shields.io badges to README and documentation homepage,
and fixed the lightbox JavaScript to exclude badges from clickable image
handling.

Changes:
- README.md: Added PyPI, Python version, MIT License, and GitHub stars badges
- docs/index.md: Added same badge set
- docs/javascripts/lightbox.js: Exclude shields.io and badge URLs from
  lightbox (badges now click through to their links)

Badge links:
- PyPI badge → PyPI package page
- Python badge → Python downloads
- License badge → MIT license info
- GitHub stars → Main repo page (for starring)

This makes the project look more professional and makes it easy for
users to star the repo, check the package on PyPI, etc.
