Codex/mc 26.2 renderFix Minecraft 26.2 render compatibility fixes

[gta66666668]

Builds on #6439 and fixes the remaining Minecraft 26.2 compatibility issues.

• Fixes VanillaTextRenderer for the 26.2 GuiGraphicsExtractor path
• Adds a Tuple compatibility shim for the current Baritone 26.1 snapshot
• Avoids writing to the now-final LevelRenderer.entityOutlineTarget field
• Uses prepareFrame(...).executeOutline() for entity shader rendering
• Passes Meteor color as outline color so shader ESP is visible again

Validation:

• ./gradlew.bat build --stacktrace passes
• Client launches locally
• Shader ESP was tested in-game and works
