/**
 * Worker entry for the project-shared blob daemon (`__omp_worker_blob_broker`).
 *
 * Hosts a {@link LocalBlobBackend} (store + exposure or uploader) plus an HTTP
 * control plane on a Unix socket. Sessions register blobs over the socket;
 * providers fetch them through the exposure. Lazy blobs resolve through a
 * loopback callback into the owning session, so nothing renders — and nothing
 * stays resident — until a provider actually asks for the bytes.
