feat: Add WYSIWYG editor components and utilities

- Implemented WysiwygModalManager for managing modals related to code blocks and block settings.
- Created WysiwygSelection for handling text selection across Shadow DOM boundaries.
- Introduced WysiwygShortcuts for managing keyboard shortcuts and slash menu items.
- Developed wysiwygStyles for consistent styling of the WYSIWYG editor.
- Defined types for blocks, slash menu items, and shortcut patterns in wysiwyg.types.ts.

+# Critical WYSIWYG Knowledge - DO NOT LOSE
+
+This document captures all the hard-won knowledge from our WYSIWYG editor development. These patterns and solutions took significant effort to discover and MUST be preserved during refactoring.
+
+## 1. Static Rendering to Prevent Focus Loss
+
+### Problem
+When using Lit's reactive rendering, every state change would cause a re-render, which would:
+- Lose cursor position
+- Lose focus state
+- Interrupt typing
+- Break IME (Input Method Editor) support
+
+### Solution
+We render blocks **statically** and manage updates imperatively:
+
+```typescript
+// In dees-wysiwyg-block.ts
+render(): TemplateResult {
+  if (!this.block) return html``;
+  // Render empty container - content set in firstUpdated
+  return html`<div class="wysiwyg-block-container"></div>`;
+}
+
+firstUpdated(): void {
+  const container = this.shadowRoot?.querySelector('.wysiwyg-block-container');
+  if (container && this.block) {
+    container.innerHTML = this.renderBlockContent();
+  }
+}
+```
+
+### Critical Pattern
+- NEVER use reactive properties that would trigger re-renders during typing
+- Use `shouldUpdate()` to prevent unnecessary renders
+- Manage content updates imperatively through event handlers
+
+## 2. Shadow DOM Selection Handling
+
+### Problem
+The Web Selection API doesn't work across Shadow DOM boundaries by default. This broke:
+- Text selection
+- Cursor position tracking
+- Formatting detection
+- Content splitting for Enter key
+
+### Solution
+Use the `getComposedRanges` API with all relevant shadow roots:
+
+```typescript
+// From paragraph.block.ts
+const wysiwygBlock = element.closest('dees-wysiwyg-block');
+const parentComponent = wysiwygBlock?.closest('dees-input-wysiwyg');
+const parentShadowRoot = parentComponent?.shadowRoot;
+const blockShadowRoot = (wysiwygBlock as any)?.shadowRoot;
+
+const shadowRoots: ShadowRoot[] = [];
+if (parentShadowRoot) shadowRoots.push(parentShadowRoot);
+if (blockShadowRoot) shadowRoots.push(blockShadowRoot);
+
+const selectionInfo = WysiwygSelection.getSelectionInfo(...shadowRoots);
+```
+
+### Critical Pattern
+- ALWAYS collect all shadow roots in the hierarchy
+- Use `WysiwygSelection` utility methods that handle shadow DOM
+- Never use raw `window.getSelection()` without shadow root context
+
+## 3. Cursor Position Tracking
+
+### Problem
+Cursor position would be lost during various operations, making it impossible to:
+- Split content at the right position for Enter key
+- Restore cursor after operations
+- Track position for formatting
+
+### Solution
+Track cursor position through multiple events and maintain `lastKnownCursorPosition`:
+
+```typescript
+// Track on every relevant event
+private lastKnownCursorPosition: number = 0;
+
+// In event handlers:
+const pos = this.getCursorPosition(element);
+if (pos !== null) {
+  this.lastKnownCursorPosition = pos;
+}
+
+// Fallback when selection not available:
+if (!selectionInfo && this.lastKnownCursorPosition !== null) {
+  // Use last known position
+}
+```
+
+### Critical Events to Track
+- `input` - After text changes
+- `keydown` - Before key press
+- `keyup` - After key press
+- `mouseup` - After mouse selection
+- `click` - With setTimeout(0) for browser to set cursor
+
+## 4. Content Splitting for Enter Key
+
+### Problem
+Splitting content at cursor position while preserving HTML formatting was complex due to:
+- Need to preserve formatting tags
+- Shadow DOM complications
+- Cursor position accuracy
+
+### Solution
+Use Range API to split content while preserving HTML:
+
+```typescript
+getSplitContent(): { before: string; after: string } | null {
+  // Create ranges for before and after cursor
+  const beforeRange = document.createRange();
+  const afterRange = document.createRange();
+  
+  beforeRange.setStart(element, 0);
+  beforeRange.setEnd(selectionInfo.startContainer, selectionInfo.startOffset);
+  
+  afterRange.setStart(selectionInfo.startContainer, selectionInfo.startOffset);
+  afterRange.setEnd(element, element.childNodes.length);
+  
+  // Extract HTML content
+  const beforeFragment = beforeRange.cloneContents();
+  const afterFragment = afterRange.cloneContents();
+  
+  // Convert to HTML strings
+  const tempDiv = document.createElement('div');
+  tempDiv.appendChild(beforeFragment);
+  const beforeHtml = tempDiv.innerHTML;
+  
+  tempDiv.innerHTML = '';
+  tempDiv.appendChild(afterFragment);
+  const afterHtml = tempDiv.innerHTML;
+  
+  return { before: beforeHtml, after: afterHtml };
+}
+```
+
+## 5. Focus Management
+
+### Problem
+Focus would be lost or not properly set due to:
+- Timing issues with DOM updates
+- Shadow DOM complications
+- Browser inconsistencies
+
+### Solution
+Use defensive focus management with fallbacks:
+
+```typescript
+focus(element: HTMLElement): void {
+  const block = element.querySelector('.block');
+  if (!block) return;
+  
+  // Ensure focusable
+  if (!block.hasAttribute('contenteditable')) {
+    block.setAttribute('contenteditable', 'true');
+  }
+  
+  block.focus();
+  
+  // Fallback with microtask if focus failed
+  if (document.activeElement !== block && element.shadowRoot?.activeElement !== block) {
+    Promise.resolve().then(() => {
+      block.focus();
+    });
+  }
+}
+```
+
+## 6. Selection Event Handling for Formatting
+
+### Problem
+Need to show formatting menu when text is selected, but selection events don't bubble across Shadow DOM.
+
+### Solution
+Dispatch custom events with selection information:
+
+```typescript
+// Listen for selection changes
+document.addEventListener('selectionchange', () => {
+  const selectionInfo = WysiwygSelection.getSelectionInfo(...shadowRoots);
+  
+  if (selectedText !== this.lastSelectedText) {
+    const range = WysiwygSelection.createRangeFromInfo(selectionInfo);
+    const rect = range.getBoundingClientRect();
+    
+    // Dispatch custom event
+    this.dispatchSelectionEvent(element, {
+      text: selectedText,
+      blockId: block.id,
+      range: range,
+      rect: rect,
+      hasSelection: true
+    });
+  }
+});
+
+// Custom event bubbles through Shadow DOM
+const event = new CustomEvent('block-text-selected', {
+  detail,
+  bubbles: true,
+  composed: true
+});
+```
+
+## 7. IME (Input Method Editor) Support
+
+### Problem
+Composition events for non-Latin input methods would break without proper handling.
+
+### Solution
+Track composition state and handle events:
+
+```typescript
+// In dees-input-wysiwyg.ts
+public isComposing: boolean = false;
+
+// In block handlers
+element.addEventListener('compositionstart', () => {
+  handlers.onCompositionStart(); // Sets isComposing = true
+});
+
+element.addEventListener('compositionend', () => {
+  handlers.onCompositionEnd(); // Sets isComposing = false
+});
+
+// Don't process certain operations during composition
+if (this.isComposing) return;
+```
+
+## 8. Programmatic Rendering
+
+### Problem
+Lit's declarative rendering would cause focus loss and performance issues with many blocks.
+
+### Solution
+Render blocks programmatically:
+
+```typescript
+public renderBlocksProgrammatically() {
+  if (!this.editorContentRef) return;
+  
+  // Clear existing blocks
+  this.editorContentRef.innerHTML = '';
+  
+  // Create and append block elements
+  this.blocks.forEach(block => {
+    const blockWrapper = this.createBlockElement(block);
+    this.editorContentRef.appendChild(blockWrapper);
+  });
+}
+```
+
+## 9. Block Handler Architecture Requirements
+
+When creating new block handlers, they MUST:
+
+1. **Implement all cursor/selection methods** even if not applicable
+2. **Use Shadow DOM-aware selection utilities**
+3. **Track cursor position through events**
+4. **Handle focus with fallbacks**
+5. **Preserve HTML content when getting/setting**
+6. **Dispatch selection events for formatting**
+7. **Support IME composition events**
+8. **Clean up event listeners on disconnect**
+
+## 10. Testing Considerations
+
+### webhelpers.fixture() Issue
+The test helper `webhelpers.fixture()` triggers property changes during initialization that can cause null reference errors. Always:
+
+1. Check for null/undefined before accessing nested properties
+2. Set required properties in specific order when testing
+3. Consider manual element creation for complex test scenarios
+
+## Summary
+
+These patterns represent hours of debugging and problem-solving. When refactoring:
+
+1. **NEVER** remove static rendering approach
+2. **ALWAYS** use Shadow DOM-aware selection utilities
+3. **MAINTAIN** cursor position tracking through all events
+4. **PRESERVE** the complex content splitting logic
+5. **KEEP** all focus management fallbacks
+6. **ENSURE** selection events bubble through Shadow DOM
+7. **SUPPORT** IME composition events
+8. **TEST** thoroughly with actual typing, not just unit tests
+
+Any changes that break these patterns will result in a degraded user experience that took significant effort to achieve.

+# Phase 2 Implementation Summary - Divider Block Migration
+
+## Overview
+Successfully migrated the divider block to the new block handler architecture as a proof of concept.
+
+## Changes Made
+
+### 1. Created Block Handler
+- **File**: `blocks/content/divider.block.ts`
+- Implemented `DividerBlockHandler` class extending `BaseBlockHandler`
+- Extracted divider rendering logic from `dees-wysiwyg-block.ts`
+- Extracted divider setup logic (event handlers)
+- Extracted divider-specific styles
+
+### 2. Registration System
+- **File**: `wysiwyg.blockregistration.ts`
+- Created registration module that registers all block handlers
+- Currently registers only the divider handler
+- Includes placeholders for future block types
+
+### 3. Updated Block Component
+- **File**: `dees-wysiwyg-block.ts`
+- Added import for BlockRegistry and handler types
+- Modified `renderBlockContent()` to check registry first
+- Modified `firstUpdated()` to use registry for setup
+- Added `injectHandlerStyles()` method to inject handler styles dynamically
+- Removed hardcoded divider rendering logic
+- Removed hardcoded divider styles
+- Removed `setupDividerBlock()` method
+
+### 4. Updated Exports
+- **File**: `blocks/index.ts`
+- Exported `DividerBlockHandler` class
+
+## Key Features Preserved
+✅ Visual appearance with gradient and icon
+✅ Click to select behavior  
+✅ Keyboard navigation support (Tab, Arrow keys)
+✅ Deletion with backspace/delete
+✅ Focus/blur handling
+✅ Proper styling for selected state
+
+## Architecture Benefits
+1. **Modularity**: Each block type is now self-contained
+2. **Maintainability**: Block-specific logic is isolated
+3. **Extensibility**: Easy to add new block types
+4. **Type Safety**: Proper TypeScript interfaces
+5. **Code Reuse**: Common functionality in BaseBlockHandler
+
+## Next Steps
+To migrate other block types, follow this pattern:
+1. Create handler file in appropriate folder (text/, media/, content/)
+2. Extract render logic, setup logic, and styles
+3. Register in `wysiwyg.blockregistration.ts`
+4. Remove hardcoded logic from `dees-wysiwyg-block.ts`
+5. Export from `blocks/index.ts`
+
+## Testing
+- Project builds successfully without errors
+- Existing tests pass
+- Divider blocks render and function identically to before

+# Phase 4 Implementation Summary - Heading Blocks Migration
+
+## Overview
+Successfully migrated all heading blocks (h1, h2, h3) to the new block handler architecture using a unified HeadingBlockHandler class.
+
+## Changes Made
+
+### 1. Created Unified Heading Handler
+- **File**: `blocks/text/heading.block.ts`
+- Implemented `HeadingBlockHandler` class extending `BaseBlockHandler`
+- Single handler class that accepts heading level (1, 2, or 3) in constructor
+- Extracted all heading rendering logic from `dees-wysiwyg-block.ts`
+- Extracted heading setup logic with full text editing support:
+  - Input handling with cursor tracking
+  - Selection handling with Shadow DOM support
+  - Focus/blur management
+  - Composition events for IME support
+  - Split content functionality
+- Extracted all heading-specific styles for all three levels
+
+### 2. Registration Updates
+- **File**: `wysiwyg.blockregistration.ts`
+- Registered three heading handlers using the same class:
+  - `heading-1` → `new HeadingBlockHandler('heading-1')`
+  - `heading-2` → `new HeadingBlockHandler('heading-2')`
+  - `heading-3` → `new HeadingBlockHandler('heading-3')`
+- Updated imports to include HeadingBlockHandler
+
+### 3. Updated Exports
+- **File**: `blocks/index.ts`
+- Exported `HeadingBlockHandler` class
+- Removed TODO comment for heading handler
+
+### 4. Handler Implementation Details
+- **Dynamic Level Handling**: The handler determines the heading level from the block type
+- **Shared Styles**: All heading levels share the same style method but render different CSS
+- **Placeholder Support**: Each level has its own placeholder text
+- **Full Text Editing**: Inherits all paragraph-like functionality:
+  - Cursor position tracking
+  - Text selection with Shadow DOM awareness
+  - Content splitting for Enter key handling
+  - Focus management with cursor positioning
+
+## Key Features Preserved
+✅ All three heading levels render with correct styles
+✅ Font sizes: h1 (32px), h2 (24px), h3 (20px)
+✅ Proper font weights and line heights
+✅ Theme-aware colors using cssManager.bdTheme
+✅ Contenteditable functionality
+✅ Selection and cursor tracking
+✅ Keyboard navigation
+✅ Focus/blur handling
+✅ Placeholder text for empty headings
+
+## Architecture Benefits
+1. **Code Reuse**: Single handler class for all heading levels
+2. **Consistency**: All headings share the same behavior
+3. **Maintainability**: Changes to heading behavior only need to be made once
+4. **Type Safety**: Heading level is type-checked at construction
+5. **Scalability**: Easy to add more heading levels if needed
+
+## Testing Results
+- ✅ TypeScript compilation successful
+- ✅ All three heading handlers registered correctly
+- ✅ Render method produces correct HTML with proper classes
+- ✅ Placeholders set correctly for each level
+- ✅ All handlers are instances of HeadingBlockHandler
+
+## Next Steps
+Continue with Phase 5 to migrate remaining text blocks:
+- Quote block
+- Code block
+- List block
+
+Each will follow the same pattern but with their specific requirements.
