Offload large trigger payloads to object storage before sending the trigger API request. The SDK uploads packets at or above the existing 128KB limit and sends an application/store pointer instead of embedding large JSON in the request body. TriggerTaskRequestBody now validates that application/store payloads are non-empty storage paths.

Payload uploads use the same resolved ApiClient as the trigger call (including requestOptions.clientConfig), not only the global apiClientManager.client — so custom baseURL, access token, and preview branch apply to both presign and trigger.
