IDE

1. Fixed an issue where switching the nine-slice fill mode of image resources did not automatically refresh in the IDE scene.
2. Fixed an issue where selecting all animation keyframes and applying “Two Tangents -> Constant” via right-click caused the editor to freeze.
3. Fixed a crash when enabling CacheAs after assigning material and shader to a sprite.
4. Fixed an issue where prefab child nodes disappeared when converting node types.
5. Fixed an error when packaging a single web project via command line.
6. Fixed an issue where lightmap baking configuration reverted to default after reopening the project.
7. Fixed an issue where renaming a prefab did not update its name in the panel.

New Features & Improvements

1. Added: A tool in the IDE for converting 3D meshes to 2D meshes.
2. Optimized: defaultPhysicsMemory global 3D configuration now supports the PhysX engine.
3. Optimized: When version management is enabled during packaging, the manifest file (fileconfig.json) for main packages and subpackages no longer uses hash-based filenames. Instead, it uses a ?v=time query parameter to ensure the latest manifest is always fetched, avoiding issues where CDN refreshes cause outdated local caches on mini game platforms.
