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

+# GiftedPrompts.vue Pre-Migration Audit
+
+## Component Overview
+- **File**: `src/components/GiftedPrompts.vue`
+- **Purpose**: Dialog component for displaying gift prompts and contact suggestions
+- **Complexity**: Medium (295 lines)
+- **Migration Priority**: High (Components category)
+
+## Current State Analysis
+
+### Phase 1: Database Migration Assessment
+- **Status**: ✅ ALREADY MIGRATED
+- **Evidence**: Uses `PlatformServiceMixin` and `this.$contacts()` method
+- **Actions Required**: None
+
+### Phase 2: SQL Abstraction Assessment
+- **Status**: ✅ NOT NEEDED
+- **Evidence**: No raw SQL queries found
+- **Actions Required**: None
+
+### Phase 3: Notification Migration Assessment
+- **Status**: ✅ NOT NEEDED
+- **Evidence**: No notification system usage found
+- **Actions Required**: None
+
+### Phase 4: Template Streamlining Assessment
+- **Status**: ⏳ NEEDS MIGRATION
+- **Issues Found**:
+  - Long CSS class `"text-center bg-gradient-to-b from-slate-400 to-slate-700 shadow-[inset_0_-1px_0_0_rgba(0,0,0,0.5)] text-white px-1.5 py-2 rounded-md mt-4"` repeated in template
+  - Template has some complex conditional logic that could be extracted
+  - Header comment formatting needs improvement
+
+## Technical Analysis
+
+### Database Operations
+```typescript
+// Already using PlatformServiceMixin
+const contacts = await this.$contacts();
+```
+
+### Template Complexity
+- **Lines**: 67 lines
+- **Conditionals**: 8 v-if statements
+- **Long CSS Classes**: 1 repeated class pattern
+- **Complex Logic**: Contact navigation and idea cycling
+
+### Script Complexity
+- **Lines**: 228 lines
+- **Methods**: 8 methods
+- **Computed Properties**: 3 (already well-structured)
+- **Data Properties**: 8 properties
+
+## Migration Plan
+
+### Phase 4: Template Streamlining
+1. **Extract Long CSS Classes**
+   - Extract button styling to computed property
+   - Ensure consistent styling across component
+
+2. **Improve Documentation**
+   - Fix header comment formatting
+   - Enhance method documentation
+
+3. **Template Optimization**
+   - Review conditional logic for potential extraction
+   - Ensure proper class binding usage
+
+## Estimated Migration Time
+- **Phase 4 Only**: 3-4 minutes
+- **Total Time**: 3-4 minutes
+
+## Risk Assessment
+- **Low Risk**: Pure UI component with no database changes
+- **No Breaking Changes**: Template streamlining only
+- **No Performance Impact**: Cosmetic changes only
+
+## Success Criteria
+- [ ] Long CSS classes extracted to computed properties
+- [ ] Header comment formatting improved
+- [ ] Template readability enhanced
+- [ ] Linting passes with no errors
+- [ ] Component functionality preserved
+
+## Migration Notes
+- Component already uses modern database patterns
+- Well-structured with good separation of concerns
+- Template streamlining will improve maintainability
+- No functional changes required
