Port to 26.3

Port to 26.3

This pr ports owo-lib to 26.3, It builds, loads into worlds and works with everything from the testclientmod, in both vulkan and openGL (as far as i have tested)

Changes

• Ported all GLFW calls to internal minecraft abstraction where possible (InputConstants). Only used direct SDL3 calls when internal abstraction didn't prove sufficient.
• Ported Blaze3D renderpipeline to the new Renderpearl call, fixed imports, mixin targets, blur and shader updates.
• Braid windows were rewritten for SDL3, separate swapchains for vulkan and opengl.
• In 26.3, Recipes are now a datapack registry so owo:remainders hook moved to the registry loader and the remainder storage is a ConcurrentHashMap now.
• Minecraft.setScreenAndShow in 26.3 forces an extra frame without the world rendered. so i switched owo's normal screen changes to gui.setScreen(...)like vanilla does.

Other bits

• Testmod validation hook moved from GlRenderPass to FrontendGpuDevice, which is where 26.3 reads IS_RUNNING_IN_IDE now.
• Bumped gradlew, dependencies and workflow.
• uwu_shaped_recipe.json5 used a recipe type nothing registers (the class is fully commented out) and an old recipe format. It used to fail quietly, 26.3 makes it fatal cause recipes are now a datapack registry, so i removed it.

Testing

• Testing done on Linux with Wayland, Nvidia with both Vulkan and OpenGL via the testclient
• owo-ui demos, config screen, context menus, scrolling, blur, layers, sliders, creative tabs, link buttons and braid inspector all worked in my testing
• no known part that doesn't work in my tests

Other

• I created the PR on the 26.2 branch since there is no 26.3 branch yet, Please change the targeted branch if you decide to merge.

Disclaimer

• LLM assistance was used in portions where i was not comfortable like braid windows swap chains and shaders porting, however the generated suggestions were reviewed by me in detail.
