Wires the prefork primitive into a CLI command. 'decnet fleet heavy' imports the shared base floor once in the master, then forks profiler + ttp as CoW-sharing child processes (own process/GIL, full isolation, shared ~71MB floor). DB-only tier => systemd unit carries no extra privilege (prefork's privilege-union cost is nil for this fleet). Unit Conflicts= the profiler/ttp units it replaces. Heavy per-worker state (ATT&CK/ML) still loads per-child; warming it in the master to share is deferred until a live RSS measurement shows the big object graph CoW-shares rather than refcount-dirties.
