v0.98.8

Added

• The capped board snapshot now carries the applied bound as task_cap, alongside the existing
  total_tasks and truncated, so a dashboard or cockpit can render a "kept / cap" gauge
  instead of only knowing the page was trimmed. Absent when the board is served without a cap.

Changed

• syn-wait now enables --mailbox by default, so every waiter launched through the alias
  recovers the directed messages that arrived while it was disconnected (a reconnect or re-arm
  gap) instead of leaving them unread until an unrelated wake. Pass --no-mailbox to opt a
  waiter out; a bare synapse arm is unchanged (mailbox off). Against a hub older than wire
  version 2 the request is ignored, so the default is safe on a mixed-version fleet.
