AuroraLite v2

Target: Minecraft Java 1.20.1 + Forge + Oculus

Install:
1. Put AuroraLite.zip into your instance's shaderpacks folder.
2. Start Minecraft with Forge + Oculus.
3. Open Video Settings > Shader Packs.
4. Select AuroraLite.

This version intentionally uses a simple composite pass for broad Iris/Oculus
compatibility and low overhead. It adds gentle bloom, contrast, color tuning,
underwater tint, and a restrained vignette.

If Oculus reports a shader compilation error, send me a screenshot of the
error screen or the latest.log/crash report and I can target that exact error.
