feat: show informational diagnostic count in the Problems panel title

Info-level (META) diagnostics are listed in the panel but weren't counted in the
title, so a file with only suggestions read "0 Problems" above a visible info
row. Count them separately and append "(N Info)" when present, e.g.
"0 typescript Problems - foo.js (2 Info)". Error/warning counts and the existing
title formats are unchanged - the suffix only appears when there are infos.
