feat: implement granular step-file workflow architecture with multi-menu support

## Major Features Added
- **Step-file workflow architecture**: Transform monolithic workflows into granular step files for improved LLM adherence and consistency
- **Multi-menu handler system**: New `handler-multi.xml` enables grouped menu items with fuzzy matching
- **Workflow compliance checker**: Added automated compliance validation for all workflows
- **Create/edit agent workflows**: New structured workflows for agent creation and editing

## Workflow Enhancements
- **Create-workflow**: Expanded from 6 to 14 detailed steps covering tools, design, compliance
- **Granular step execution**: Each workflow step now has dedicated files for focused execution
- **New documentation**: Added CSV data standards, intent vs prescriptive spectrum, and common tools reference

## Complete Migration Status
- **4 workflows fully migrated**: `create-agent`, `edit-agent`, `create-workflow`, and `edit-workflow` now use the new granular step-file architecture
- **Legacy transformation**: `edit-workflow` includes built-in capability to transform legacy single-file workflows into the new improved granular format
- **Future cleanup**: Legacy versions will be removed in a future commit after validation

## Schema Updates
- **Multi-menu support**: Updated agent schema to support `triggers` array for grouped menu items
- **Legacy compatibility**: Maintains backward compatibility with single `trigger` field
- **Discussion enhancements**: Added conversational_knowledge recommendation for discussion agents

## File Structure Changes
- Added: `create-agent/`, `edit-agent/`, `edit-workflow/`, `workflow-compliance-check/` workflows
- Added: Documentation standards and CSV reference files
- Refactored: `create-workflow/steps/` with detailed granular step files

## Handler Improvements
- Enhanced `handler-exec.xml` with clearer execution instructions
- Improved data passing context for executed files
- Better error handling and user guidance

This architectural change significantly improves workflow execution consistency across all LLM models by breaking complex processes into manageable, focused steps. The edit-workflow transformation tool ensures smooth migration of existing workflows to the new format.
