feedback7 R22-LATE: while a facing is chosen, Enter follows the focus — ✕ cancels, any other button does nothing, the wheel confirms; golden: unchanged

GitHub #394 / PR #395 by @Xinglan233. The wheel's capture listener committed the previewed direction on Enter whatever
had the focus, so Tab to 准备 / 设置 / the exit button / ✕ and Enter deployed (the PR let only a focused ✕ keep its
native Enter). Now gameLogic facingEnter decides: Enter on ✕ cancels; on any other control (button, link, form field,
ARIA control) it is swallowed — the wheel already holds Space and the shortcuts; elsewhere it commits the previewed
direction, and does nothing while none is previewed. The wheel (role="dialog") takes the focus when it opens
(tabIndex -1, no focus ring over the screen), so a button focused before the drop cannot swallow the confirming Enter
and the first Tab reaches ✕; nothing restores the old focus when it closes (a restored 准备 would take the next key).

Docs: PLAYING.md's key paragraph. Tests: test/ui/feedback5-hotkeys.test.js (facingEnter and its wiring, 2 new);
test/ui/facing.e2e.test.js (SP_E2E, the PR's drag / Tab flow, 4 cases: run here in headless Chrome, 4/4 pass, 4/4 fail
on the parent — Enter on the focused exit button deployed). Golden unchanged (client only).
