A command longer than the input field used to clip silently at the right edge, hiding the cursor and the command tail. Now the single logical input line scrolls horizontally to keep the cursor in view, with muted `<` / `>` markers at the reserved edge columns signalling hidden content on either side. The offset is a pure function of (line length, cursor column, field width, previous offset) — input_scroll_offset — so the view only moves when the cursor would leave the window, and one column is held on each side for the markers so a marker never hides the cursor. The stored App::input_scroll_offset resets when the buffer is replaced wholesale (submit, history recall). The ADR-0027 6-column indicator reserve is preserved. Tests: pure-offset cases, tail-visible + head-visible render checks, and the reset-on-submit/history check. One layout snapshot now shows a long command's tail instead of its clipped head.
