v0.2.0-beta3-26.3+fabric

As this is still a beta version, this version can contain bugs. Feel free to report ANY misbehaviours and errors!

• the GPU part transform checks its first vertices against the game's own on your GPU and turns off if any differ
• F3 mobium:modules shows what that check compared, for bug reports from GPUs not tested yet
• Mobium loads only on Minecraft 26.3.x; it loaded on 26.4 snapshots before, where it was never tested
