* 🚀 ci: publish coverage badge and docs badge

* 🚀 ci: publish coverage badge and docs badge

* 📝 docs: add commit signing badge to README

* 🐛 ci: fix Python here-document syntax in coverage extraction

- Replace here-document with python3 -c for better shell compatibility
- Fix 'unexpected EOF' and 'delimiter not found' errors in GitHub Actions
- Maintain same functionality with more reliable syntax

* 🔄 ci: switch from coverage to test success rate badge

- Replace coverage-based badge with test success rate calculation
- Use passed/total test ratio for more reliable metrics
- Update README badge label from 'Coverage' to 'Tests'
- Maintain same gist file and color thresholds (95%+ green, 80%+ yellow, <80% red)
