GHSA-j497-x9hr-x34x: RabbitMQ amqp091-go: Silent Data Truncation and State Corruption via Shortstr Integer Overflow

## Summary A data integrity and protocol corruption vulnerability exists in the AMQP client's property serialization logic. When encoding AMQP short string (`shortstr`) fields—such as identifiers, routing strings, and content metadata—the length of the string is explicitly cast to a fixed-size 8-bit unsigned integer (`uint8`). If an application provides a property string exceeding 255 bytes, the length counter silently wraps around (e.g., a length of 300 wraps to 44). …
