Junegunn Choi e873128d93 Add inline header/header-lines/footer borders inside the list frame ...

Adds a new BorderShape, BorderInline, accepted as a value for
--header-border, --header-lines-border, and --footer-border. When the
surrounding --list-border has both top and bottom horizontals (rounded,
sharp, bold, double, horizontal), the corresponding section is rendered
inside the list frame separated from the list content by a horizontal
line whose endpoints join the list border as T-junctions. Without a
compatible list border, the shape falls back to BorderLine.

Supports:
  - All three layouts (default, reverse, reverse-list).
  - Any combination of the three inline sections, producing stacked
    separators.
  - --header-label and --footer-label rendered on their separator row
    (and redrawn on reqRedrawHeaderLabel / reqRedrawFooterLabel).
  - Section-specific border colors on the separator line, with the
    T-junction characters painted in the list-border color so the outer
    frame stays visually continuous.

Rejects the combinations that do not make sense:
  - --input-border=inline / --list-border=inline / --preview-border=inline
  - --header-first + (--header-border=inline | --header-lines-border=inline)
  - --header-border=inline with a non-inline --header-lines-border
    (inline has to propagate inward toward the list content).
