- Add github.com/goccy/go-yaml dependency (v1.19.2)
- Update parsePersona to detect format by file extension
- Support both .yaml and .yml extensions (case-insensitive)
- Convert built-in personas to YAML format
- Add comprehensive tests for YAML parsing
- Update README with YAML examples and documentation

and supports comments, making persona definitions more readable.
JSON remains supported for backwards compatibility.
