feat: Complete TestDrive-JSUI migration - Main app now uses capability

Phase 3 Complete: Updated templates to use capability location exclusively

Changes:
- Update document.html: Changed 2 script src paths to use capabilities/testdrive-jsui/js/
  * core/debug-system.js → capability location
  * main.js → capability location

- Update edit-mode-fixed.html: Changed 7 script src paths to use capability location
  * core/debug-system.js, section-manager.js → capability
  * components/debug-panel.js, dom-renderer.js → capability
  * config-loader.js, main-updated.js → capability

- Update testdrive-jsui submodule to include Phase 1 & 3 migration

Verification:
✅ View mode rendering tested - all paths use capability
✅ Edit mode rendering tested - assets deploy from capability via plugin
✅ No old markitect/static/js/ references in generated HTML
✅ All 84 automated tests passing

Migration Status:
- Phase 1: ✅ Complete (files copied to capability)
- Phase 2: ⏭️ Skipped (comprehensive testing in Phase 1)
- Phase 3: ✅ Complete (templates updated, main app migrated)
- Phase 4: ⏸️ Ready (original files can be removed after verification)

Impact:
- Main MarkiTect app now exclusively uses capability for JavaScript UI
- Original files in /markitect/static/js/ preserved for rollback safety
- No breaking changes - all rendering modes work correctly
