Split LpIuma's AI Studio Gemini runs into their own combinations; add PR template; register Kimi mythos run

Per PR #2's description those two pelicans were generated in Google AI
Studio, not AntiGravity — they move to gemini-3-1-pro-aistudio and
gemini-3-5-flash-aistudio entries (harness Google AI Studio, High).
XA2333's unknown-environment runs stay where they were, disclaimed in
their notes. Adds a bilingual PR template asking for harness/effort/
one-shot info up front, and registers the new Kimi K2.6 mythos-craft
artifact (16 combinations ran).
