Preserve scrollback for partial scroll regions starting at top (#4941)
* Preserve scrollback for partial scroll regions starting at top
When a partial scroll region starts at row 0 (the top of the viewport),
lines scrolled off the top were silently discarded via viewport.remove(0)
instead of being transferred to lines_above (the scrollback buffer).
This affected both add_canonical_line and rotate_scroll_region_down.
Applications like Codex CLI use partial scroll regions to push rendered
content into terminal scrollback (via DECSTBM + newlines). In tmux,
these lines are preserved in the scrollback buffer and accessible via
copy-mode scrolling. In Zellij, they were lost, causing mouse wheel
scrolling to show only stale pre-application content.
Transfer lines to lines_above when scroll_region_top == 0 and alternate
screen is not active, matching the behavior of tmux.
* add selection handling to CSI S, add matching handling for CSI M, add tests
* add pr
