- Add Roo Modes support with --output-format roo option
- Create comprehensive Roo Modes prompt template (src/prompts/roo_modes.md)
- Update CLI to support roo output format alongside cursor and cline
- Update rules generation logic to handle different output formats
- Fix repomix to output single file instead of folder (-o flag)
- Update LLM generator to use correct prompts and tag extraction for each format
- Add Roo Modes documentation to README with examples and features
- Support for .roomodes YAML configuration files
