Add IDE support and comprehensive documentation for the eval test framework:
- Create eval.schema.json with definitions for all 9 check types
- Update README.md with detailed check type reference and examples
- Add $schema reference to all 7 fixture eval.json files
The schema enables autocomplete and validation in VS Code and other
editors when editing eval.json files.
