Register Mistral Medium 3.5 × Vibe (Thinking)

Two one-shot runs generated in the Vibe web app (Mistral's renamed
Le Chat, Thinking enabled), contributed by Nagi-ovo.

mythos-craft is a fixed build (1 line changed): the world synchronously
built the full RENDER_DISTANCE=4 ring (9x9 = 81 chunks) on load, each
chunk doing an O(voxels x structures) linear scan over mythStructures
for all 16x16x128 voxels, so the main thread froze before the first
frame and the page never opened. RENDER_DISTANCE 4 -> 1 (a 3x3 = 9-chunk
first-screen load) lets it open at 60fps; terrain/visuals/gameplay are
the model's original output, otherwise unmodified. pelican-cycling is
unmodified. Both documented in the run notes; READMEs updated.
