fix(notes): [[ completes a note link, the way # completes a project

Typing [[ did nothing. The toolbar hint offered "[[ another note" and the parser
turned a fully-typed [[Title]] into a link on save, but the completion that makes
it usable — the one # has for projects — was never there, so you had to know and
type a note's title exactly, brackets and all.

Now [[ opens the same picker # does, over the notes the page has loaded: the
current note is left out (a note linking to itself is a loop nobody meant), and
one without a title yet cannot be pointed at. Choosing a note closes its own
brackets — the opener is already in the text — and leaves a space, so the next
word is a word and not more of the tag. On save the link is real and shows in the
note's links, not merely as text.

The picker's two kinds are told apart where a project wears its colour: a note
suggestion wears the brackets that open it.

e2e: [[ offers a note by title, choosing it writes [[Title]] into the note, and
the link lands in the note's links. Full Chromium suite green.
