BatchRunRequest

Request to fan out N cycles from a WorkPlan (blueprint).

Field	Type	Description
`count`	`integer \| null`	Launch N identical cycles from the WorkPlan
`client_ids`	`string (uuid)[] \| null`	One cycle per client (overrides count); capped at 500
`all_clients`	`boolean`	Fan one cycle across every active client in the workspace (overrides count)
`input_data`	`object`	Shared runtime inputs (e.g. period, label) show nested Empty object.
`topic_id`	`string (uuid) \| null`	Bind all batch cycles to this topic. When set every cycle is created with topic_id so it emits live events to the topic channel and appears on the topic canvas (thinking, steps, artifacts). NULL cycles are invisible to the topic canvas even though they execute normally.
