Fixed
- Fixed pane scrollbars so they reserve their own lane instead of drawing over terminal content, which makes scrolling and scrollbar dragging behave more cleanly in narrow panes.
- Fixed alternate-screen scrollback handling so full-screen terminal apps can preserve recoverable history inside herdr panes instead of losing rows that scroll off.
- Fixed Codex in herdr panes losing transcript/history while running in alternate screen, so past output remains scrollable instead of disappearing as the session grows.
- Hid the rendered terminal cursor while a pane is scrolled back, avoiding stray cursor blocks appearing in the wrong place during history navigation.
