/**
 * AI autocomplete API — inline code completions for notebook cells.
 *
 * Routes live under /api and are auth-protected like the rest of the API.
 * Backed by the nebula-autocomplete engine, which drives a Claude Code / Codex
 * CLI using the user's own subscription. The CLI can run in one of two places:
 *
 *   - on THIS server (default) — when the Nebula host itself has claude/codex
 *     (a local install, or a login node where the CLIs are available);
 *   - on the USER'S machine over the reverse SSH tunnel ("run on my machine") —
 *     for remote Nebula where the user would rather use their own laptop's CLI +
 *     subscription. See the `transport` field on the completion request.
 *
 * Engines are created lazily and cached per (backend, transport) so a warm pool
 * is reused across turns; disposed on server shutdown.
