fix: restore recent languages analyzer for GitHub Events API changes

Implements PR lowlighter#1754 fix using direct REST API commit fetching:
- GitHub Events API removed commit details from push payloads (Aug 2025)
- Uses REST API endpoints to fetch commits directly per repo/branch
- Builds wanted map for selective commit fetching with early exit
- Filters commits by authoring email safely using optional chaining
- Fetches full commit details with file patches for language analysis
- Verified working with multiple languages across repositories
