The branch permission check was only allowing feat/, feature/, and dev/
prefixes for write operations. This blocked PR creation from fix/*
branches, forcing fallback to direct API calls.
Added patterns:
- fix/, bugfix/, hotfix/ - for bug fixes
- chore/, refactor/ - for maintenance
- docs/, test/ - for documentation and tests
