Lost Signal VHS

Critical Minecraft 26.2 compatibility fix

Lost Signal VHS v1.6.1 fixes the corrupted blue/white world image that appeared when the shader was enabled on Minecraft 26.2 with Iris 1.11.2.

Fixed

• Added explicit lightweight geometry passes so Iris always supplies the real vanilla-lit scene to the VHS post-processing pipeline.
• Made all temporal framebuffer read/write flips explicit.
• Verified shader toggle off/on, alpha-tested foliage, temporal history, and the full VHS pipeline in a live Minecraft 26.2 world.

Included

• Complete v1.6 roadmap: Liminal Signal, tape generations, period camcorders, and broken-signal simulation.
• Support for Minecraft 26.2, 26.1.2, 1.21.11, 1.21.4, 1.21.1, and 1.20.1.

Minecraft 26.2 users should update immediately. Use OpenGL; Iris does not support the experimental Vulkan backend.
