Two fixes to the just-shipped collapse toggles:
- They lived inside the centre StatusbarHost, so they shifted when a pane
collapsed and the bar resized. Move them to the OUTER status-bar row ends
(screen edges) so they stay put. StatusbarHost reverts to its prior layout.
- The toggle was a const widget that read isCollapsed in its own build; Flutter
skips identical const children on rebuild, so the chevron never flipped. Pass
collapsed/visible in from the parent's arrangement listener so it rebuilds and
the chevron tracks the action direction. A 'flips live' test now guards it.

Fixed ~24px caret-line cells bookend the status bar (left=sidebar, right=context);
chevron flips per arrangement.isCollapsed (inward=collapse, outward=expand) and
fires the existing sidebar.collapse / context.collapse commands — the mouse
affordance for the already keyboard/CLI-addressable action (D-6). Visual only;
no new collapse logic. Status items shift 28px inward for the reserved cells.
