Trinity Nano Base GSM8K AdamW-LoRA profile gate

This repo currently preserves the 8xH200 profile-gate artifacts for the Trinity Nano Base baseline. The full run is intentionally not uploaded yet because the best measured 8-GPU profile reached only about 0.95% estimated MFU at per-device batch size 8, with max memory around 131.8 GiB per H200.

See best_profile.json and the profiles directory for throughput, memory, W&B URLs, and adapter/profile artifacts.
