feat(gitea): implement gitea_coder role with scope enforcement
Implements the gitea_coder role with full file/branch operations and commit message generation.
Features:
- Branch creation with scope gating (prevents main pushes)
- Enforces branch naming conventions (feature/, fix/, refactor/, etc.)
- Generates detailed commit messages with ticket references
- Creates PRs from branches
- Reads ticket requirements from issues
- Unified file operations workflow
Technical:
- Uses existing gitea/dev.py operations
- Validates branch names against scope patterns
- Auto-generates commit messages with issue references
- Caches default branch per chat_id for session persistence
