♻️ refactor: migrate from custom coverage to orgoro/coverage action

- Replace custom coverage_report.py script with orgoro/[email protected] GitHub Action
- Generate XML coverage format instead of JSON/LCOV for better action compatibility
- Remove codecov action and custom GitHub API integration
- Add coverage thresholds: 80% overall, 90% for new files
- Remove custom coverage configuration from pyproject.toml
- Update .gitignore to use coverage.xml format
- Simplifies maintenance and provides better PR coverage reporting
