On iOS Safari/PWA, tapping the terminal opened the on-screen keyboard but
keystrokes were silently dropped. After the earlier CSS fix (c7266b7f) the
helper textarea now covers the terminal surface and iOS focuses it natively
on tap — but the bubble-phase onPointerDown/onTouchStart handler kept
re-focusing xterm + the textarea and calling setSelectionRange during the
touch gesture. That is the same class of re-focus-mid-gesture that the
prior commit identified as disrupting iOS input attribution; moving from
capture to bubble phase wasn't enough.
- Early-return from handleTerminalGestureFocus on
(hover: none) and (pointer: coarse), so iOS handles focus with no JS
interference.
- Desktop (fine pointer) keeps the existing behavior because the textarea
stays 1x1 off-screen and still needs programmatic focus on canvas click.
- Add a regression test covering the no-op path with the media query mocked.
