OnDisconnect class

What the server should do with path if this client goes away without saying goodbye.

Registered with the server now and carried out by it on disconnect, which is the only cleanup that survives a device losing power rather than shutting down — nothing on the device gets to run at that point.

The future completes when the registration lands. Whether the server later carries it out is not something a client can observe.
