feat: Add Common Tiles Reference and Enhance Asset Management

- Introduced a new common_tiles.txt file for AI agents, providing a customizable reference for various tile types used in projects.
- Updated CMake configuration to improve asset copying for macOS and non-Apple platforms, ensuring agent assets are correctly placed in the output directory.
- Enhanced the AssetLoader to support additional search paths for asset retrieval, improving cross-platform compatibility.
- Improved error handling in the AgentEditor for missing prompt files, providing clearer instructions for users on file locations and creation.
