feat: Add support for team: format and comprehensive tests (#81)

* feat: Add support for team: format and comprehensive tests

- Update TEAM_REGEX to support team: format (without @ symbol)
- Add comprehensive test suite for all team annotation formats
- Test edge cases, invalid inputs, performance, and cross-platform compatibility
- Ensure backward compatibility with existing @team and @team: formats
- Add 7 new test functions covering 220+ lines of test code
- All 68 tests pass, including new comprehensive test suite

This addresses GitHub issue #131 and adds the requested team: format
for better Ruby magic comment consistency.

* refactor: Simplify tests to use existing test_team_regex function

- Remove redundant test functions (test_comprehensive_team_formats, test_team_annotation_edge_cases, etc.)
- Update existing test_team_regex to include new team: format tests
- Reduce change from ~220 lines to ~22 lines while maintaining same functionality
- All 61 tests pass with minimal, focused change
