docs: reorganize documentation structure with 7-item folder limits

- Create logical sub-folder classification for all documentation
- Organize 91 migration files into component-specific folders
- Separate user guides, build system, migration, and development docs
- Maintain maximum 7 items per folder for easy navigation
- Add comprehensive README and reorganization summary
- Ensure all changes tracked in git with proper versioning

Structure:
- user-guides/ (3 items): user-facing documentation
- build-system/ (3 items): core, platforms, automation
- migration/ (6 items): assessments, testing, templates
- development/ (4 items): tools and standards
- architecture/, testing/, examples/ (ready for future docs)

Total: 24 folders created, all within 7-item limits

+# EntityIcon.vue Migration Audit
+
+## Component Overview
+- **File**: `src/components/EntityIcon.vue`
+- **Size**: 45 lines (Low Complexity)
+- **Purpose**: Icon generation component for contacts and entities using DiceBear avatars
+- **Migration Target**: Enhanced Triple Migration Pattern
+
+## Migration Status: ⏳ READY FOR MIGRATION
+
+### Pre-Migration Analysis
+- **Database Operations**: ✅ No databaseUtil imports found (pure UI component)
+- **SQL Queries**: ✅ No raw SQL queries found
+- **Notification Usage**: ✅ No notification system usage found
+- **Template Complexity**: ✅ No long CSS classes found (simple template)
+
+### Migration Requirements
+- ✅ **Phase 1**: Database Migration - NOT NEEDED (no database operations)
+- ✅ **Phase 2**: SQL Abstraction - NOT NEEDED (no raw SQL)
+- ✅ **Phase 3**: Notification Migration - NOT NEEDED (no notifications)
+- ✅ **Phase 4**: Template Streamlining - NOT NEEDED (simple template)
+
+### Component Features to Migrate
+- **Icon Generation**: Profile image display or DiceBear avatar generation
+- **CORS Handling**: Image URL transformation for cross-origin requests
+- **Fallback Logic**: Blank square SVG for missing identifiers
+- **Responsive Sizing**: Dynamic icon size handling
+- **Contact Integration**: Contact object property access
+
+### Technical Analysis
+- **Database Operations**: None (pure UI component)
+- **Notification System**: None (no notifications used)
+- **Template Classes**: Simple template with no long CSS classes
+- **Methods**: 1 method with good functionality
+- **Computed Properties**: None (uses method instead)
+- **Props**: 4 props with proper TypeScript typing
+
+### Migration Complexity Assessment
+- **Database Migration**: Low (no database operations)
+- **SQL Abstraction**: Low (no raw SQL)
+- **Notification Migration**: Low (no notifications)
+- **Template Streamlining**: Low (simple template)
+- **Overall Complexity**: Low
+
+### Estimated Migration Time
+- **Conservative Estimate**: 2-3 minutes
+- **Optimistic Estimate**: 1-2 minutes
+- **Based on**: Simple component, no migration needed
+
+### Risk Assessment
+- **Risk Level**: Low
+- **Potential Issues**: None identified
+- **Dependencies**: @dicebear/core, @dicebear/collection, Contact interface
+- **Testing Requirements**: Icon generation, image display, fallback behavior
+
+### Migration Strategy
+1. **Documentation Review**: Enhance existing documentation
+2. **Code Quality**: Improve method documentation
+3. **Type Safety**: Ensure proper TypeScript usage
+4. **Validation**: Ensure icon generation works correctly
+
+### Success Criteria
+- ✅ Component functionality preserved
+- ✅ Icon generation works correctly
+- ✅ Image display works correctly
+- ✅ Fallback behavior works correctly
+- ✅ Lint validation passes
+
+### Next Steps
+- ⏳ Review and enhance documentation
+- ⏳ Validate functionality
+- ⏳ Create migration completion document
+
+## Migration Notes
+- Component is already well-structured
+- No actual migration needed (all phases already compliant)
+- Focus on documentation enhancement
+- Component is ready for human testing
