fix(tabs): say a reply will WAKE you with a new message (clearer than 'arrives on its own')

Matches actual behavior: a peer's reply wakes this tab with a new message in a
later turn. Updated the send_to_tab description (both canReadTab branches), the
delivery-result text (both branches), and the system-prompt one-liner; updated
the test assertion accordingly.
