search UX: visible prompt + incremental (as-you-type) highlighting

- Fix overlap: #search, #status and Footer all docked bottom, and Input defaults
  to a 3-row bordered widget squeezed into 1 row. Now the search bar is a clean
  1-row (border:none) that REPLACES the status line while active (status hidden),
  so the query is always visible.
- Incremental search: highlight all matches + preview-jump from the origin on
  every keystroke (Input.Changed), not just on submit. Disasm indexes once then
  each keystroke is instant. Enter keeps; empty Enter repeats last; Esc cancels
  and restores the origin cursor + status line.
- pilot suite 23/23 (adds: bar-visible/no-overlap, incremental-before-Enter,
  Esc-cancel).
