fix(cmdatom): "!" operator hardcodes its range #41451

Problem:
The "!" operator stuffs its cmdline continuation (`:.,.+1!`), so its
frame ends before capture (stuff pending) and the redo-prep disappears
with it.

    !ipsort<CR> => { type='excmd', lhs=':.,.+1!sort<NL>', keys=':.,.+1!sort<NL>' }

Compare to builtin "." which works bc `do_bang()` completes the redo
(`!ip` + `sort<NL>`).

Solution:
Appoint the stuffed continuation frame as the "redo-prep" frame.

    !ipsort<CR> => { type='operator', operator='!', lhs='!ipsort<NL>', keys='!ipsort<NL>' }

Notes:
- atom_cmd_end(): a frame ending with stuff pending re-points its
  redo-prep to the next frame.
- atom_cmd_start(): a stuffed continuation frame (`KeyStuffed`) keeps
  the redo-prep; flushed stuff discards it.
