fix(hud): ask the model only with a place label, catch flush English echoes

- Skip the model when the view has layers but no place, street or nearby
  label: with layers alone it invented a place.
- The English-echo check treats only Latin letters as part of a word, so
  ids flush against kana or Han and hyphenated names are caught; it skips
  nominal, state words a locale keeps in English and names inside place
  labels.
- Outside English, per-layer state ids are left out of the request.
- The ja/zh cap steps back to the start of a Latin word, not the last space.
- Fold the CJK cap cases into hudSummaryResponse.test.mjs.
