Accept + persist the now-populated host-report storage_targets. Minimal — the authoritative storage manifest is hub-owned (slice 10); this mirrors what the agent observes. - hostReportPayload.StorageTargets: full mirror of the agent's hub.StorageTarget wire contract; persisted verbatim in report_json (no schema change); count + WARN on disconnected targets. - shared host-report golden updated with two populated targets; byte-identical with felhom-agent's copy. - TestHostStorageTarget_GoldenContract: hub half of the bidirectional key-set test.
