The vllmScripts repository (LLM inference fleet: serve scripts, systemd
units, env tunables, deployment runbook, research docs) is merged into
this repository. Its full history is grafted under llm/ with a
two-parent merge commit so no commit is lost.
A follow-up commit reorganizes llm/ into the repo layout:
llm/docs -> docs/LLM, llm/scripts -> scripts, llm/old -> old.
