…tocomplete

This commit introduces a new plugin-based architecture for the MemoEditor,
enabling modular feature development and improved code organization.

## Core Changes

### New Plugin System
- Created `core/EnhancedEditor.tsx`: Base editor with plugin lifecycle
- Created `core/editor-types.ts`: Type definitions for plugins
- Created `plugins/` directory: Modular plugin architecture

### Plugins Implemented
- **Slash Commands Plugin** (`/` trigger)
  - Text formatting: bold, italic, strikethrough, code
  - Headings: H1-H3
  - Lists: bullet, numbered, todo
  - Block elements: quote, divider, table, code block
  - Text alignment and clear editor action

- **List Autocomplete Plugin** (Tab/Enter key)
  - Automatic list continuation with Tab
  - Suggests: bullet, numbered, todo (checked/unchecked)

- **Tag Suggestions Plugin** (`#` trigger)
  - Tag suggestions based on existing tags

### UI/UX Improvements
- Character count display in editor
- Improved suggestion menu with keyboard navigation
- Better placeholder handling with null coalescing
- Streamlined event handling with onKeyDown callback

### Code Quality
- Added comprehensive i18n keys for all editor commands
- Fixed TypeScript types for better type safety
- Consistent code style across all files

### Files Added
- `MemoEditor.tsx`: Complete editor container with plugin integration
- `core/EnhancedEditor.tsx`: Enhanced editor with plugin lifecycle
- `core/editor-types.ts`: Plugin system type definitions
- `plugins/index.ts`: Central plugin exports
- `plugins/slash-commands/`: Slash commands implementation
- `plugins/list-autocomplete/`: List autocomplete
- `plugins/tag-suggestions/`: Tag suggestions

### Files Modified
- `index.tsx`: Updated to use new plugin-based editor
- `components/EditorContent.tsx`: Added onKeyDown prop
- `types/components.ts`: Made onKeyDown optional
- `state/Editor.tsx`: Removed Tab handling (now in plugins)
- `locales/en.json` & `zh-Hans.json`: Added command translations

### Breaking Changes
- Removed internal toolbar (toolbar now handled by plugins)
- Changed `onConfirm/onCancel` to `onSubmit` prop
- Removed save logic from editor (simplified to onSubmit callback)

Change responsive breakpoint from md (768px) to lg (1024px) so that
toolbar buttons show only icons on narrower screens, not just mobile.

- AI buttons: compact mode now active below lg (1024px)
- VisibilityToggleGroup: label text hidden below lg
- Focus mode button: visible only above lg

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Fix "dual state" issue where mobile header and desktop navbar
both appeared between sm (640px) and lg (1024px) breakpoints,
causing duplicate logos.

Changes:
- RootLayout: sm → lg for desktop navbar visibility
- GeneralLayout: !sm → !lg for mobile header visibility

Now consistent with MemoLayout, AIChatLayout, ScheduleLayout
which already use lg breakpoint.
