- New 📁 toolbar button toggles on-canvas visibility of group frames (node.properties.showGroups).
When off, group frames aren't drawn and aren't grabbable on the canvas — but groups still appear
in the Overview tree. State persists and is restored on load. Groups are never exported regardless.
- Dragging a multi-selection in the Overview now shows live feedback WHILE dragging (not just on
release): every dragged row fades, and a small pill follows the cursor showing "N regions → <target>"
(the group/region you're about to drop onto, or "→ root"). Cleared on drop/cancel/teardown.
JS parses clean.
