llm.kittens

Carry the in-flight port of llm.c onto ThunderKittens forward. Use whenever the user asks to implement the next milestone, port a kernel, add a TK wrapper, or modify llmc/* or train_*.cu in this repo.

Drive the llm.kittens H100 validation harness — pick the right phase, set the required env vars, replay captured evidence, and avoid `goal-complete` mistakes. Use whenever the user asks to validate the goal, run a phase of `scripts/validate_goal_h100.sh`, replay an existing log, or check whether a milestone gate would pass.
