lerko f89ca8acb9 feat(tui): add split-pane detail, compact date headers, and input drawer
Three layout improvements for better space utilization:

- Compact date headers: date labels render as left gutter column instead
  of standalone lines, saving one line per date group in stream view
- Input drawer: capture bar expands to 4-line drawer with border, hints,
  and live preview of parsed entity/search query
- Split-pane detail: wide terminals (>=100 cols) show list and detail
  side-by-side with h/l focus switching, falling back to full-screen
  detail on narrow terminals
