Bug: SQS Handler Errors and Inefficiencies

The SQS handler has several issues:

1. Incorrect Task Status on Error: When an error occurs during SQS message processing, the task status is not updated to TaskState.Failed and remains in TaskState.Working.
2. Improper SQS Handler Return Type: The handler incorrectly returns an API response (createApiResponse) which is unsuitable for SQS event processing; SQS handlers should return void or throw errors.
3. Single Record Processing: The return statement inside the for loop causes the handler to exit after processing only the first SQS record, preventing subsequent records in the same event from being processed.
4. Potential Serialization Failure: JSON.stringify(result) in the success path may fail if result contains circular references or other non-serializable data, causing unexpected task failures.

Bug: SQS Handler Fails to Process Batch Records

The SQS handler only processes the first record in a batch due to an early return. Error handling is insufficient: JSON.parse lacks protection for malformed SQS message bodies, the initial task status update to Working is unhandled, and task status is not set to Failed on errors. Additionally, the handler incorrectly returns HTTP responses, which is inappropriate for SQS events.
