Keyboard
- Only jump to the app when the voice surface is shown (tab tap / opened
there); typing tabs no longer leave the host on keyboard open.
- Wait up to 0.4 s for the arbiter to report the host app before leaving,
and late-bind an id that arrives within 6 s of the jump.
- Empty arbiter callbacks no longer wipe an already captured host id;
install the capture handler in every build configuration.
App
- Return to the previous app with up to four retries using iOS's real
open result, and honor the skip-app-switch preference.
- Keep the pending host id across cold-start zombie reconciliation, and
expire it after two minutes (legacy values without a timestamp stay valid).
- Show a light tip pointing at the system back control when we cannot
return automatically ("点击返回，立即使用").
Tests: TTL behaviour and return retry policy.
