Defined in: filtering/tree/filter-tree-drag-state.service.ts:118
Find the deepest branch body under (x, y) and compute its active zone.
“Deepest” = innermost nested branch. In document order, a child branch body always appears AFTER its ancestor bodies, so the last matching candidate is the deepest.
