Subject: [PATCH] feat(overlays): pin llama-cpp-rocm to am17an/mtp-clean fork

Override the unstable llama-cpp-rocm src to track the am17an/llama.cpp
mtp-clean branch (rev 267f8af). Replaces upstream's leaveDotGit-based
COMMIT extraction with a direct postFetch write so the source hash is
deterministic without a git clone. The fork's webui package-lock differs
from upstream, so npmDepsHash is repinned.
