// admin-bootstrap.mjs
//
// Service container for the standalone memind_adm process.
//
// Builds only the domain services the back-office routes need (user-auth, LLM
// providers, and the minimal plaza graph behind the ops console). It deliberately
// does NOT start any user-facing daemons — no thumbnail watcher, no asset-sync
// watcher, no plaza hot-score scheduler, no goosed auto-sync. Those belong to the
// public server. Side-effecting actions (e.g. push selected LLM key to goosed)
// stay behind explicit admin routes.
//
// The same factory functions imported here are the ones server.mjs uses, so the
// domain logic has a single source of truth; only the wiring differs.
