llama-cpp: use nodejs_latest

Pinned the web UI build to nodejs_latest because the current nodejs lts (v24.15.0)
has an ESM-loader file-descriptor regression (https://github.com/nodejs/node/issues/62012)
that throws EBADF on fstat and, on darwin, aborts the vite/SvelteKit build
with a libuv kqueue assertion.
