v0.30.0

Added

• synapse wait --wake-jitter <seconds> (default 8): a broadcast wakes every
  terminal at once, so their agents all re-invoke and hit the model-provider API in
  the same instant — and the provider rate-limits the burst. The waiter now adds a
  random 0..jitter delay before exiting on a broadcast wake, spreading the
  re-invocations so each reacts without the synchronised stampede; a one-to-one
  directed message still wakes immediately. Set 0 to disable.
