Merge branch 'origin/main' into feature/elicitations

Resolved conflicts by adopting the improved form input handling from main:
- Standardized JsonSchemaType.required to only accept string arrays (JSON Schema standard)
- Adopted enhanced object and array rendering with proper nested support
- Improved boolean field rendering (removed extra wrapper div)
- Enhanced array handling with add/remove functionality
- Simplified required field validation logic

This maintains elicitation functionality while benefiting from the form input fixes.
