guest-diag: vsock pin stream (guest pagemap -> host sema_map_add)
The guest-agent exec path is too slow under driver-init load (a 15k-page
window scan took 17-35 s to complete), so GR window pins landed after the
channels' entries had been consumed and after the client's cuCtxCreate
timeout. The guest now scans /proc/<pid>/pagemap locally and streams only
delta runs over vsock (no agent on the hot path); the host listener pins
them as they arrive. The scanner writes a pidfile so restarts do not kill
the new instance.
