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>

/**
|
||||
* Base Control Class for TestDrive-JSUI Controls
|
||||
*
|
||||
* Provides common functionality for positioning, drag, resize, expand/collapse operations.
|
||||
* This is the foundation class that all UI controls inherit from to ensure consistent
|
||||
* behavior across the TestDrive-JSUI component system.
|
||||
*
|
||||
* Key Features:
|
||||
* - Drag and drop positioning with compass-based anchoring
|
||||
* - 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.
