workspace_tree_rebalancer.go RawHistoryFolder

1// workspace_tree_rebalancer.go - Simplified no-op tree rebalancer placeholder.
2//
3// The original TreeRebalancer relied on SafeWidget abstractions. Until a
4// pointer-based implementation is restored, we keep a lightweight stub so the
5// rest of the workspace code can continue to depend on the API without
6// carrying dead logic.
