Terminal-style input history for the DeepSeek Harness web composer: edge-first arrows with exact draft/caret restore, browser-local persisted history, Ctrl+R reverse search, workspace recall - and sliding-context awareness (compaction summaries in recall/search, compaction notice with one-click /compact fill).
Composer expand/collapse toggle for DeepSeek Harness (dsh): a ⬆/⬇ button in the composer tool row grows the input to a tall 70vh writing view for long drafts.
DSH Web GUI layout fix: composer (input bar + bottom status bar) leaves the scroll region — message scrolling stops above the input bar, the scrollbar no longer covers the input area
