feat(hub): say "N groups unreachable" on Search for a few seconds, not for goodHEAD0.18main

The line sat above the results for as long as the page was open. It is now
said once a cross-group pass is over, for five seconds, in the same passing
note as "Link copied" — moved out of copy-link.js into note.js (`say(text,
ms)`), one note at a time for the whole page. The `.search-unreachable` rule
goes with the line it styled.

The copy-link probe now also checks in Chrome that the note goes by itself.
