/**
 * Hub entry — skeleton.
 *
 * Wires the provider-agnostic agent seam end-to-end with a no-op Feishu read, so
 * the invariant path is exercised without live credentials. Real wiring (Fastify
 * server, Feishu OAuth/event callbacks, Prisma, admin-web) lands incrementally;
 * this file proves the seam compiles and the pieces connect.
