Fix TUI layout for halfwidth Japanese sound marks

What changed

  • Use Ratatui-compatible terminal widths throughout TUI layout, preserving
    full-width counters for long lines.
  • Wrap and truncate on grapheme boundaries so halfwidth kana sound marks and
    emoji sequences stay intact.
  • Apply the corrected sizing to text input, selection popups, status and
    history cells, Markdown, hyperlinks, and scrollable cloud diffs.

Testing

  • Add focused unit and snapshot coverage for wrapping, truncation, cursor and
    mask alignment, popup columns, status output, session headers, Markdown
    tables, process output, and scrollable diffs.
