Finish the Minecraft 26.2 rendering port

[I-No-oNe]

Type of change

• Bug fix
• New feature

Description

Completes the Minecraft 26.2 rendering migration after the rendering submission API changes.

Rendering helpers now receive only the dependencies they use: PoseStack and SubmitNodeCollector. RenderWorldEvent remains at event boundaries and carries only the pose stack, camera, delta tracker, and geometry collector. The port also updates renamed Minecraft and Mixin targets, moves custom world geometry submission into LevelRenderer.submitFeatures, and replaces the removed immediate buffer drawing path.

Validation:

• ./gradlew build passes with Java 25.
• The development client reaches the title screen without Mixin or rendering initialization crashes.
• RenderWorldEvent parameters remain only on actual event handlers.
• git diff --check passes.
