/**
 * Single source of truth for the CLI's Node-version policy.
 *
 * Lobu's SDK sandbox (query_sdk / run_sdk) uses isolated-vm, whose native addon
 * is tied to each Node line's V8 ABI: isolated-vm@6 covers Node 22–24, the
 * aliased isolated-vm@7 covers Node 26+. Node 25 is an EOL non-LTS line upstream
 * skipped, so it boots but has no sandbox build. Below 22 nothing works — the
 * bundled server's deps (undici via @sentry/node) reference globals absent on
 * old Node and crash on load.
 *
 * The `bin/lobu.js` entrypoint carries an inline copy of the MIN threshold
 * because it must run with zero imports (before the bundle loads); keep it and
 * packages/server/src/utils/assert-node-version.ts in sync with this file.
