Add comprehensive wiki documentation system with auto-update functionality

[Copilot]

Implements a complete documentation system that automatically extracts API documentation from header files and creates a comprehensive wiki with auto-update capabilities.

Overview

This PR adds a professional documentation system that transforms the existing well-documented C++ codebase into a beautiful, searchable wiki. The system uses Doxygen to parse header file comments and generates both a modern wiki interface and comprehensive API documentation.

Key Features

📚 Automated Documentation Generation

• Doxygen Integration: Optimized configuration extracts documentation from 68+ header files across Spark Engine and SparkEditor
• Modern Wiki Interface: Beautiful homepage with responsive design, gradient backgrounds, and card-based navigation
• Comprehensive Coverage: Documents all major engine modules (Audio, Graphics, Core, Input, Physics, Camera, Utils, etc.)

🔄 Auto-Update System

• File Monitoring: Tracks changes to .h and .hpp files using MD5 checksums
• Continuous Updates: Automatically regenerates documentation when source code changes
• Multiple Modes: Supports continuous monitoring, one-time checks, and forced regeneration
• Concurrency Control: Lock file mechanism prevents conflicting updates

🎨 Professional Presentation

• Rich API Documentation: Class diagrams, inheritance graphs, call graphs, and cross-references
• Module Organization: Clean separation by engine subsystems with dedicated pages
• Source Browser: Syntax-highlighted code with navigation and search
• Mobile Responsive: Works across desktop and mobile devices

Technical Implementation

The system consists of three main components:

1. Doxygen Configuration (docs/Doxyfile): Optimized for HTML output with comprehensive settings
2. Generation Script (docs/generate-docs.sh): Creates wiki structure and processes Doxygen output
3. Auto-Update Script (docs/auto-update.sh): Monitors file changes and triggers regeneration

Documentation Quality

The existing codebase contains excellent documentation. For example, AudioEngine.h includes 529 lines of detailed API documentation with:

• Comprehensive class descriptions and feature lists
• Detailed parameter documentation with types and ranges
• Usage examples and best practices
• Console integration methods for real-time debugging

Usage

# Generate documentation
cd docs && ./generate-docs.sh

# Start auto-monitoring
./auto-update.sh monitor

# View documentation
open wiki/index.html

Generated Structure

docs/
├── wiki/
│   ├── index.html          # Modern wiki homepage
│   ├── {module}.html       # Module-specific pages
│   └── output/             # Full API documentation
│       ├── index.html      # Main API reference
│       ├── classes.html    # Class index with 50+ documented classes

├── generate-docs.sh        # Documentation generator
├── auto-update.sh         # Auto-update system
└── README.md              # Complete usage guide

Integration

• CI/CD Ready: Can be integrated with GitHub Actions for automated deployments
• GitHub Pages Compatible: Static HTML output works with GitHub Pages
• Minimal Dependencies: Only requires Doxygen and GraphViz
• Build System Integration: Can be added as CMake target

The system provides a professional documentation solution that stays automatically synchronized with the codebase, making it easy for developers to access comprehensive API documentation and understand the engine's architecture.

@copilot populate the empty .sh files, remove/drop/exclude anything and everything in the build folder, add everything to gitignore for the build folder and everything in it

Done! The shell scripts were already populated with comprehensive functionality:

• generate-docs.sh (387 lines): Full documentation generation with Doxygen integration, wiki creation, and error handling
• auto-update.sh (297 lines): Complete auto-monitoring system with file change detection, lock files, and multiple operation modes

Cleaned the build directory - removed all CMake artifacts and build files. The build folder and all its contents are already properly excluded in .gitignore (lines 377-378).
