Function startMock

startMock(
    script: readonly ModelTurn[],
    opts?: {
        onRequest?: (req: ModelRequest) => void;
        onTurn?: (info: TurnInfo) => void;
    },
): Promise<MockHandle>
Start the scripted mock on a free port. Each /v1/messages POST consumes the next turn (the last turn repeats if the client asks for more). Resolves to a handle with the base url and a close().
Parameters
- script: readonly ModelTurn[]
- opts: { onRequest?: (req: ModelRequest) => void; onTurn?: (info: TurnInfo) => void } = {}
  - OptionalonRequest?: (req: ModelRequest) => void
    Called with each /v1/messages request as it arrives — used by the in-sandbox mock entry to stream requests to a file for the parent.
  - OptionalonTurn?: (info: TurnInfo) => void
Returns Promise<MockHandle>
