Fix action execution - resolve screen path and traverse default subscreens

Critical fixes:
- Set resolvedScreenDef after successful literal path resolution (was falling back to webroot)
- Traverse default subscreens when looking up transitions (matching action discovery logic)
- Build full path including subscreens for framework transition execution

New features:
- moqui_batch_operations tool for multi-step workflows
- Enhanced validation error handling with field-level details
- ARIA mode now includes value, ref, description, describedby attributes

Documentation:
- Added render modes table and examples to AGENTS.md
- Updated README with MARIA format explanation
- Added MCP_SERVICE_DOCS wiki space with service parameter docs
