Struct ProbeGate 

pub struct ProbeGate;

Readiness::Probe: one agent round trip, which is the whole of what this shape can observe.

GuestAgent::sync_clock is that round trip — its Ok means the agent accepted a connection, parsed a frame and replied — and it is what the cold-boot path used as its readiness gate before the guest learned to dial out. Its side effect is one the boot wants anyway.

Transport-independent, so every factory that answers Readiness::Probe returns this rather than its own.
