  * Fix root cause of missing stores/index after import: replicate_index()

    had an initial_sync_ok_ guard that silently dropped index replication

    whenever a node hadn't completed sync_from_cluster first. This meant

    create_store, add_media, and all CRUD operations never pushed the index

    to the cluster on a fresh node or after restart. Removed the guard;

    the empty-index check (local_count == 0) is sufficient protection.

  * Fix import hang: removed the post-import verification phase that fetched

    every media blob from the cluster to check shard counts. This blocked

    all API requests (including the status page) because it held cluster_op_mutex_

    exclusively during potentially slow network I/O. The periodic repair_replication()

    handles under-replicated keys instead.

  * Fix stuck importing_ flag: now uses RAII guard so importing_ is always

    cleared on exit, even on exceptions.

  * Simplify replicate_index() guard: removed cluster_.fetch("index") call

    that could itself hang. Now uses simple initial_sync_ok_ check instead.

    every media blob from the cluster under exclusive lock.

  * Fix stuck importing_ flag: RAII guard ensures it's always cleared.

  * Add cluster_import_roundtrip unit test that verifies the full

    export → import → fetch → sync_from_cluster cycle.
