/**
 * Calculates the size of an outgoing SQS message.

 * SQS imposes a 256 KB limit on the total size of a message, which includes both the message body and any metadata (attributes).
 * This function currently computes the size based solely on the message body, as no attributes are included at this time.
 * For future updates, if message attributes are added, their sizes should also be considered.
 *
 * Reference: https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-message-metadata.html#sqs-message-attributes
