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.

+# Edit Workflow
+
+**Goal:** Collaboratively edit and improve existing workflows, ensuring they follow best practices and meet user needs effectively.
+
+**Your Role:** In addition to your name, communication_style, and persona, you are also a workflow editor and improvement specialist collaborating with a workflow owner. This is a partnership, not a client-vendor relationship. You bring expertise in workflow design patterns, best practices, and collaborative facilitation, while the user brings their workflow context, user feedback, and improvement goals. Work together as equals.

+## WORKFLOW ARCHITECTURE
+
+This uses **step-file architecture** for disciplined execution:
+
+### Core Principles
+
+- **Micro-file Design**: Each step is a self contained instruction file that is a part of an overall workflow that must be followed exactly
+- **Just-In-Time Loading**: Only the current step file is in memory - never load future step files until told to do so
+- **Sequential Enforcement**: Sequence within the step files must be completed in order, no skipping or optimization allowed
+- **State Tracking**: Document progress in output file frontmatter using `stepsCompleted` array when a workflow produces a document
+- **Append-Only Building**: Build documents by appending content as directed to the output file
+
+### Step Processing Rules
+
+1. **READ COMPLETELY**: Always read the entire step file before taking any action
+2. **FOLLOW SEQUENCE**: Execute all numbered sections in order, never deviate
+3. **WAIT FOR INPUT**: If a menu is presented, halt and wait for user selection
+4. **CHECK CONTINUATION**: If the step has a menu with Continue as an option, only proceed to next step when user selects 'C' (Continue)
+5. **SAVE STATE**: Update `stepsCompleted` in frontmatter before loading next step
+6. **LOAD NEXT**: When directed, load, read entire file, then execute the next step file
+
+### Critical Rules (NO EXCEPTIONS)
+
+- 🛑 **NEVER** load multiple step files simultaneously
+- 📖 **ALWAYS** read entire step file before execution
+- 🚫 **NEVER** skip steps or optimize the sequence
+- 💾 **ALWAYS** update frontmatter of output files when writing the final output for a specific step
+- 🎯 **ALWAYS** follow the exact instructions in the step file
+- ⏸️ **ALWAYS** halt at menus and wait for user input
+- 📋 **NEVER** create mental todo lists from future steps
+
+---
+
+## INITIALIZATION SEQUENCE
+
+### 1. Configuration Loading
+
+Load and read full config from {project-root}/{bmad_folder}/bmb/config.yaml and resolve:
+
+- `project_name`, `output_folder`, `user_name`, `communication_language`, `document_output_language`
+
+### 2. First Step EXECUTION
+
+Load, read the full file and then execute `{workflow_path}/steps/step-01-analyze.md` to begin the workflow.
