v3.7
add: double-clicking either split-view pane now runs the same explicit pane alignment command as Ctrl+Y
change: split-view scrolling is stable and independent by default; Ctrl+Y and the context-menu sync command remain the explicit best-effort alignment actions
fix: find bar keyboard access, Escape closing, close button visibility, button tooltips, and shortcut/help/menu documentation are kept consistent
fix: help overlay scrolling is contained so wheel input does not leak through to the underlying document view
