Bug fixes

• The :causation_id dispatch option is now honored on persisted events. Previously it was silently overridden by the dispatched command's command_uuid, which made chain-of-causation impossible to reconstruct from events alone for multi-event flows (closes #624). When :causation_id is not supplied, the command's own command_uuid is still used as the fallback — so default behaviour is unchanged. This also fixes a latent bug where process-manager- and event-handler-dispatched commands passed the originating event's id as :causation_id (see process_manager_instance.ex:229 and Commanded.Event.Handler examples), but it was being thrown away before persistence.

• Fix race condition in batch processing where timer could fire during batch handling

• Buffer and timer now cleared before processing to prevent stale state
