Wire InfoCommand through as one real, runnable example

BambuRequest::Info(InfoCommand) is now live (was commented out) —
examples/bambu_protocol_demo.rs constructs one, serializes it, and prints
it next to Bambu's real wire JSON for comparison. Run it and copy this
exact shape (proto message -> use it here -> add an enum variant) for
every other command.
