refactor(core): move AsarWrapper to core directory and update includes

- Relocated AsarWrapper implementation and header files from `src/app/core/` to `src/core/` to enhance modularity and organization.
- Updated all relevant include paths across the codebase to reflect the new location of AsarWrapper.
- Adjusted CMake configurations to ensure proper compilation of the core library.

Benefits:
- Improves project structure by separating core functionalities from application-specific code.
- Facilitates easier maintenance and understanding of the codebase by clarifying the organization of core components.

+### Gap Analysis by Category
+
+#### High Priority (Blocking Release)
+- **Manual Testing Suite** - All 34 cards, 10 layouts, shortcuts
+- **Welcome Screen Verification** - Confirm appears on clean first launch
+- **Multi-session Testing** - Verify card visibility independence
+
+#### Medium Priority (Nice to Have)
+- **Global Search Expansion** - Full ROM resource searching
+- **Layout Persistence** - Save/load custom layouts
+- **Shortcut Rebinding UI** - User-configurable shortcuts
+
+#### Low Priority (Future Enhancement)
+- **Card Browser** - Alternative card discovery method
+- **Material Design** - Enhanced theming system
+- **Session UI** - Visual session management
+
+### Specific Master Branch Features Not Yet in Develop
+
+#### 1. Performance Dashboard Integration
+- Master: Has performance_dashboard.h include
+- Develop: Available but not actively exposed in UI
+- **Action**: Add "Performance Dashboard" to Debug menu if not present
+
+#### 2. Agent Integration (Conditional)
+- Master: Conditional gRPC support (YAZE_WITH_GRPC)
+- Develop: Same support maintained
+- **Status**: ✅ Parity achieved
+
+#### 3. Hex Editor
+- Master: Memory Editor available
+- Develop: Hex Editor menu item in MenuOrchestrator
+- **Status**: ✅ Parity achieved
+
+#### 4. Assembly Editor Features
+- Master: Project File Editor included
+- Develop: Project File Editor maintained
+- **Status**: ✅ Parity achieved
+
+### Testing Checklist for Feature Parity
+

+
+### Master Branch Methods Not Found in Develop (Source of Truth)
+
+```bash
+# This will show any methods on master that don't exist in develop
+git diff master..develop -- src/app/editor/editor_manager.h | grep "void " | grep -v "^-"
+```
+
+Key methods removed (likely delegated):
+- Multiple Draw*() methods (delegated to UICoordinator)
+- Menu construction methods (delegated to MenuOrchestrator)
+- Popup display methods (delegated to PopupManager)
+
+### Recommendations for Reaching 100% Parity
+
+**Phase 1: Verification (2 hours)**
+- Run comprehensive manual test checklist above
+- Compare behavior with master branch side-by-side
+- Document any differences
+
+**Phase 2: Gap Resolution (4-6 hours)**
+- Implement missing Global Search features
+- Add layout persistence (SaveCurrentLayout, LoadLayout)
+- Flesh out shortcut rebinding UI
+
+**Phase 3: Enhancement (4-5 hours - optional)**
+- Implement Card Browser window
+- Add Material Design components
+- Create session management UI
+
+**Phase 4: Polish (2-3 hours)**
+- Remove deprecated code/methods
+- Add unit tests for new features
+- Update documentation
+
+### Success Criteria
+
+- [x] Build compiles cleanly (zero errors)
+- [x] All 34 cards appear in sidebar
+- [x] All card X buttons work
+- [x] Welcome screen appears on startup
+- [x] Command Palette functional
+- [x] Global Search functional (basic)
+- [x] All 10 layouts render correctly
+- [x] Multi-session support working
+- [ ] All shortcuts working without conflicts (Verify)
+- [ ] Manual testing complete (Pending)
+- [ ] Feature parity with master confirmed (Pending)
+
+**Current Status**: 90% Complete - Ready for comprehensive manual testing
