Detailed Description

MPI server (rank 0): dispatches DET sequences to worker clients.

The server runs on MPI rank 0 and does not execute RELAP5 simulations itself. It handles metadata only: restart data stays on the client that produced it and moves client to client. The server keeps a queue of metadata-only restart tasks and assigns them to free clients round-robin. Clients announce new branch points with server_branch_meta (local id + branch count), report a finished sequence with server_done_with_report (a SequenceReport), and confirm a finished peer transfer with server_send_complete. Restart blobs reach the server only while it gathers a checkpoint or dispatches the pending tasks of a resumed one.
