Use tmux to list keybindings (#6308)

* Use tmux to list keybindings

* Annotate tmux keybindings

* List unannotated bindings too and let the isolated server exit on its own

list-keys -aN falls back to the raw command when a binding has no note,
so user-added bindings in an existing tmux.conf still show up. Dropping
exit-empty off means the throwaway server exits when the client
disconnects instead of relying solely on the trap.
