feat: switch input source during prefix mode (#434)

On macOS, opt-in under [experimental], temporarily switch the host input
source to the current ASCII-capable layout while prefix mode is active so
prefix commands register even when a CJK IME is composing, then restore the
previous input source when prefix mode exits or is cancelled. No-op when the
current source is already ASCII-capable, on non-macOS platforms, or when any
input source call fails. Pane text input is unaffected.

Also pin next_resize_poll in next_loop_deadline_includes_selection_autoscroll_deadline
so the selection autoscroll deadline stays the earliest; the default resize
poll could otherwise beat it and flake the assertion.
