Restores the fork's PLE offload package (not upstream) and its pull
transport: the offload process holds no CUDA context; the captured op waits on
a device-mapped host flag and copies host->GPU on the model stream; publication
is fenced; releases are synchronous across dummy/capture work; failures close
the rank. Includes the test-only fault-injection cuts for the transport.
