Strip MiMo's embedded model name from its artifacts (blind-Arena identity leak)

MiMo v2.5 Pro's one-shot outputs wrote the model name into the browser
title, an on-screen "Generated by MiMo v2.5 Pro" caption, a console log
(mythos-craft.html) and a watermark text at the bottom of the SVG
(pelican-cycling.svg), which would reveal its identity during blind
Arena voting. Removed those identity strings; generation logic untouched.
Documented the surgical fix in both run notes. MiMo was the only entry
with a visible model-name leak.
