DataTree.serializeNode walked the tree recursively, one frame per znode
level, which does not scale to very deep trees. Rewrite it as an iterative
pre-order traversal over an explicit heap stack, removing the dependency on
tree depth. Traversal order, per-node locking and emitted records are
unchanged, so the on-disk snapshot format is identical. Adds a regression
test that serializes a very deep chain on a small-stack thread and checks it
round-trips.
