+ * Tests for buildDeployMap — the pure tree-computation core inside
+ * useOrgDeployState.
+ *
+ * Issue: #742 (buildDeployMap unit tests, #2071 follow-up).
+ *
+ * The function takes a flat list of NodeProjections and a set of
+ * deletingIds, then computes per-node OrgDeployState:
+ *   isActivelyProvisioning — node itself is provisioning
+ *   isDeployingRoot       — node is a root AND has provisioning descendants
+ *   isLockedChild         — node is a deleting child OR a non-root in a deploying tree
+ *   descendantProvisioningCount — total provisioning descendants (roots only)
+ *
+ * Coverage:
+ *   §1  Empty input
+ *   §2  Single node — no parent, non-provisioning
+ *   §3  Single node — no parent, provisioning
+ *   §4  Single node — has parent (parent exists)
+ *   §5  Parent not in projections → node treated as root
+ *   §6  Two nodes: root (non-provisioning) + child
+ *   §7  Two nodes: root (provisioning) + child
+ *   §8  Three-level tree: grandparent (provisioning) → parent → child
+ *   §9  DeletingIds contains a non-root node → isLockedChild=true
+ *   §10 DeletingIds contains the root → root isLockedChild=true
+ *   §11 Two independent roots, one provisioning
+ *   §12 Provisioning count: root has 2 provisioning descendants
+ *   §13 Non-root node with provisioning status → isActivelyProvisioning=true
+ *   §14 findRoot memoization: repeated calls don't re-walk the chain
+ *   §15 deletingIds + provisioning interact: deleting takes isLockedChild
+ *   §16 Child of provisioning root (not itself provisioning) → isLockedChild=true
+ *   §17 Deep chain (5 levels), no provisioning → all nodes unlocked
+ *   §18 Deep chain (5 levels), middle node is provisioning root
