- Updated the physics module to include Box2D support, enabling management of physics bodies and collision events. - Enhanced the map module to support tile layers and improved hot-reload functionality for tilemaps. - Updated documentation to reflect the new features in the physics and map systems, including usage examples and API references. - Modified CMakeLists.txt to include new modules for physics and font management, ensuring proper build configurations.
