v0.58.1

Fixed

• The shell hook no longer collides with a worker-session tmux waker on the
  <identity>-rx name. The prompt auto-arm and the interactive provider's own
  tmux waker both tried to own that waiter; the passive one won the name while
  the injecting one was locked out, so a terminal agent (Codex, Kimi K2) never
  auto-woke on a directed message. The prompt auto-arm now yields when a live
  worker-session tmux waker is present, and the provider wrapper releases the
  passive waiter before launching the provider, so the injecting waker owns the
  name. Re-run synapse install-shell-hook to pick up the change.
