RabbitMQ Library Fails on Reconnect Despite Production-Ready Looks

A developer's RabbitMQ client library with 1,200 lines of code and features like automatic reconnection and circuit breakers had never survived a connection drop. An audit revealed multiple critical bugs, including a reconnection path that didn't restore the channel pool and a rate limiter that crashed on its own feature. The library also registered process exit handlers, risking application shutdown on any unhandled rejection.
