/**
 * E2E harness for TREK's critical user flows (FE7).
 *
 * Two web servers are orchestrated: the Express/Nest backend on :3001 against an
 * isolated throwaway SQLite DB (e2e/server-launch.mjs sets TREK_DB_FILE + seeds a
 * known admin), and the Vite dev server on :5173 which proxies /api, /uploads,
 * /ws to the backend. Tests run serially against one worker so they share the
 * single seeded database deterministically.
