1. Graphics System Completion - Unify backend management and optimize rendering pipeline
2. Engine Core Cleanup - Refactor main engine loop and state management
3. Physics Optimization - Improve performance and add advanced constraints
4. UI Framework - Complete the modern UI system
5. Tool Suite - Finish asset processor and visual editor

• Removed ~50 redundant documentation files
• Eliminated duplicate code files
• Cleaned up build artifacts
• Updated file references in build system
• Established clear module boundaries
• Reduced maintenance overhead significantly

• src/root.zig removed - use src/mod.zig directly
• src/nyx_std.zig removed - use standard Zig std library
• Some file paths updated in build system
• Excessive status documentation removed

This changelog consolidates information from 30+ previous status reports and completion documents that were removed during the cleanup phase.
