fix(cli): skip output-history replay on terminal resize

_resize_clear_ghosts (introduced in NousResearch#20444) replays _OUTPUT_HISTORY after
every SIGWINCH to recover conversation content lost by the screen clear.
This causes a jarring "re-streaming" effect — all recent output lines,
including streaming tokens and spinner frames, are reprinted in rapid
succession whenever the user maximizes/restores the terminal window
(Command+Enter on macOS).

Change _recover_after_resize to only clear the screen + reset the
renderer, without replaying output history.  prompt_toolkit's native
_on_resize handler redraws the input area and status bar cleanly.

Users who want to see conversation history restored after resize can
still press Ctrl+L (/redraw), which calls _force_full_redraw (that path
still includes _replay_output_history).

Fixes the symptom reported in NousResearch#19280 where resize recovery replays
entire conversation as if it were streaming from the beginning.
