Clean up references to deleted scripts and pattern system

- Removed references to validate-references.sh from YAML files
- Removed expand-references.sh from settings.local.json
- Cleaned up @pattern/@flags references from shared files
- Updated documentation to reflect current no-code implementation
- Simplified reference-index.yml to remove @include patterns

This cleanup removes confusion from the abandoned pattern reference
system while maintaining all functionality.
