refactor: the hub is neshub everywhere

Six comments across nescope, neswire and nescapture still named
nestri-guest-hub, plus one still naming nestri-protocol. Deferred from the
import commits so the rename would read as one change rather than six
unexplained edits inside otherwise-verbatim trees.

Comments only. Realigned an ASCII box in encode.rs that the shorter name
knocked crooked.
