feat: enhance ControlBase with advanced panel behavior patterns

Implement comprehensive control panel functionality based on reference patterns: ## New Features - Icon-only collapsed state with compass positioning - Expand/drag functionality for repositioning panels - Bottom-left corner resize with minimum size constraints - Collapse button returns to original position - Header toggle for content visibility control ## Technical Improvements - Enhanced DOM structure with expanded/collapsed states - Robust event handling with automatic cleanup - State management for drag, resize, expand operations - Position restoration system for collapse behavior - Comprehensive styling system with backdrop effects ## Components Added - Enhanced ControlBase class with 5 core behaviors - ContentsControl, StatusControl, EditControl, DebugControl panels - Component discovery system with TDD implementation - Legacy DocumentControlsLegacy for backward compatibility ## Testing & Documentation - Interactive test page for behavior validation - Comprehensive implementation notes - TDD test suite with 84 passing tests - Component listing automation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+
+## Enhanced ControlBase Architecture
+
+### Overview
+The ControlBase class has been significantly enhanced to provide advanced panel behavior patterns based on the reference implementation in `relicts/DebugControlContent.html`. This creates a modern, interactive foundation for all UI control panels.
+
+### Key Features Implemented
+
+#### 1. Icon-Only Collapsed State
+- **Behavior**: Controls start as compact 40px icon buttons
+- **Styling**: Clean design with subtle shadows and hover effects
+- **Positioning**: Compass-based positioning (N, NE, E, SE, S, SW, W, NW)
+- **Implementation**: `control-toggle` button with icon display
+
+#### 2. Expand/Drag Functionality
+- **Behavior**: Click icon expands to full panel; drag header to reposition when expanded
+- **Event Handling**: Proper event delegation prevents conflicts
+- **Position Tracking**: Maintains drag offset for smooth movement
+- **Implementation**: `startDrag()`, `handleDrag()`, `stopDrag()` methods
+
+#### 3. Bottom-Left Corner Resize
+- **Behavior**: Resize handle (↙) appears in bottom-left when expanded
+- **Constraints**: Minimum 200px width, 150px height
+- **Direction**: Bottom-left resize (expand down and left)
+- **Implementation**: `addResizeHandle()`, resize event handlers
+
+#### 4. Collapse with Position Restoration
+- **Behavior**: Close button (✕) returns to original compass position
+- **State Management**: Clears drag positioning, restores transform/positioning
+- **Cleanup**: Removes resize handles and event listeners
+- **Implementation**: `collapse()` method with `originalPosition` restoration
+
+#### 5. Header Toggle for Content Visibility
+- **Behavior**: Click title toggles content area visibility
+- **States**: Full expanded vs header-only modes
+- **Preservation**: Maintains expanded state while hiding content
+- **Implementation**: `toggleHeaderOnly()` method
+
+### Technical Architecture
+
+#### State Management
+```javascript
+this.isExpanded = false;      // Icon vs expanded panel
+this.isHeaderOnly = false;    // Header-only vs full content
+this.isDragging = false;      // Drag operation active
+this.isResizing = false;      // Resize operation active
+this.originalPosition = null; // Compass position storage
+```
+
+#### DOM Structure
+```html
+<div class="control-panel">
+  <button class="control-toggle">🔧</button>           <!-- Icon state -->
+  <div class="control-panel-expanded">                 <!-- Expanded state -->
+    <div class="control-header">
+      <span class="control-icon">🔧</span>
+      <span class="control-title">Control</span>
+      <button class="control-close">✕</button>
+    </div>
+    <div class="control-content">...</div>
+  </div>
+</div>
+```
+
+#### Event Handling Strategy
+- **Tracked Events**: Automatic cleanup with `eventHandlers` Map
+- **Global Events**: Separate tracking for drag/resize (`_dragHandlers`, `_resizeHandlers`)
+- **Event Prevention**: `stopPropagation()` and `preventDefault()` where needed
+- **Conflict Resolution**: State checks prevent overlapping operations
+
+### Usage for Derived Controls
+
+Controls inherit all functionality by extending `ControlBase`:
+
+```javascript
+class MyControl extends ControlBase {
+    constructor() {
+        super();
+        this.config = {
+            icon: '📊',
+            title: 'My Control',
+            position: 'ne',
+            className: 'my-control'
+        };
+    }
+
+    buildContent() {
+        const content = this.element?.querySelector('.control-content');
+        if (content) {
+            content.innerHTML = `<div>Custom content here</div>`;
+        }
+    }
+}
+```
+
+### Integration Points
+
+#### With TestDrive-JSUI System
+- **Component Discovery**: Listed by `scripts/list_components.py`
+- **TDD Testing**: Validated by `tests/test_component_listing.py`
+- **Legacy Support**: `DocumentControlsLegacy` maintains backward compatibility
+
+#### With MarkiTect md-render
+- **Plugin Integration**: Ready for deployment via Makefile targets
+- **Asset Deployment**: CSS/JS bundling for production use
+- **Edit Mode**: Enhanced interactive editing experience
+
+### Testing
+
+#### Test Page: `test-control-base.html`
+- Interactive demonstration of all 5 behaviors
+- Multiple controls in different compass positions
+- Real-time functionality validation
+
+#### Automated Testing
+- Component listing tests ensure discovery
+- Integration tests validate interaction patterns
+- Legacy tests maintain backward compatibility
+
+### Performance Considerations
+
+#### Event Management
+- Automatic cleanup prevents memory leaks
+- Efficient event delegation reduces overhead
+- State-based operation prevention avoids conflicts
+
+#### DOM Manipulation
+- Minimal DOM changes during state transitions
+- CSS-based styling reduces JavaScript overhead
+- Lazy content building improves initial load
+
+### Browser Compatibility
+
+#### Modern Features Used
+- `getBoundingClientRect()` for precise positioning
+- CSS transforms for smooth positioning
+- Event delegation patterns
+- CSS backdrop-filter (with fallbacks)
+
+#### Fallback Strategy
+- Graceful degradation for older browsers
+- Feature detection where necessary
+- Progressive enhancement approach
+
+This enhanced ControlBase provides a solid foundation for modern UI control panels while maintaining compatibility with existing systems.

+ * - Resize handles with hover-based visibility
+ * - Expand/collapse state management
+ * - Safe operation wrappers with error handling
+ * - Development mode with strict error checking
+ * - Accessibility support with proper ARIA labels
+ *
+ * Dependencies:
+ * - None (standalone base class)
+ *
+ * Usage:
+ * Controls inherit from this base by using Object.create(Control) and
+ * implementing their specific buildContent() methods.

+<p>The JavaScript controls should:
+1. Initialize successfully with proper error handling
+2. Display accurate document statistics
+3. Provide interactive drag/resize functionality
+4. Work with the debug system integration
+5. Handle errors gracefully per the Guardrail Principle</p>
