Greptile Summary

The PR introduces an MQTT transport and packet-codec library with Swoole-backed server/client implementations, MQTT 3.1.1 and 5.0 encoders, property handling, documentation, tests, and containerized CI.

• Correctly distinguishes receive timeouts, terminal socket errors, and peer closure in the client lifecycle.
• Tracks active Swoole connections in shared memory across workers and independently of application callbacks.
• Pins the GitHub Actions dependencies to immutable commit SHAs.
• Adds MQTT packet encoding, parsing, property support, and unit and end-to-end coverage.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
