Remove the non-working session-switching keybinds ctrl+x n (New) and
ctrl+x l (Sessions) and their action methods; /new and /sessions are still
reachable by typing them (with the inline hints) or via the palette. The
keybind field is cleared on both commands so hints/palette stop showing
them. ctrl+x q/c/t (quit/compact/thinking) are left intact.
