muse-tracker 0.0.10

• Task roots follow the agent's last activity. The tasks query now pages
  on end (tasksTimeColumn: "end"), so an agent's row comes back whenever
  it does something new. Roots of agents that started before the first export
  window now get their input, kind, session and status, and a root's status and
  final answer stay current instead of freezing at the agent's start.
• Langfuse: a child span waits until its task's row has been seen, so every span
  carries the task's session and tags (childrenHeld in export and status).
• Setup version 5: rewrite queries.tasks to page on end; Braintrust installs
  then re-send task roots once to repair those already sent.
