The right-Ctrl rescue existed because some layouts claim that key and deliver
the chord as a bare letter, but it only covered what the *screens* answer: the
letter table listed ^R and ^P, while ^C and ^V were bound straight to their own
handlers above the dispatcher. So on the affected layouts right Ctrl-V typed a
`v` into the compose line and right Ctrl-C did nothing — the two chords a user
is most likely to reach for with the right hand.
Both now funnel through _dispatch like every other key, and the letter table is
the single source of truth for both halves of a chord's life: the Keys.Control*
bindings are generated from it, and the rescue reads it. Adding a chord is one
line, and a chord can no longer be bound without its rescue — or rescued into an
action nothing binds. `quit` and `paste_clipboard` are answered in the
dispatcher and never forwarded, so no screen sees them.
m/i/h stay out of the table on purpose: prompt_toolkit spells Enter, Tab and
Backspace as ControlM/ControlI/ControlH, so claiming them would rebind those.
