With depth = time, #agents/3d drew subagents behind the session that
spawned them. A subagent took the mtime of its meta.json, which is
rewritten when it finishes, and a session took the moment the hub first
saw its name, or the window end when it had none.
Sessions now take the first line of their transcript and subagents the
first line of theirs, both from /api/subagents, with the old values as
fallback. SpaceView.notBeforeParent moves a spawned node without a time,
or with one before its parent's, to its parent's time, nested subagents
included, so no subagent lies before the agent that spawned it. The 3D
signature carries the time, so the nodes move once the lifetimes load.
