📄 Description

Overview

Adds a "Serialization" section to the messages guide covering how to serialize and deserialize LangChain message objects using dump()/load() (JS) and dumpd()/load() (Python). This addresses a long-standing gap where there was no documentation on persisting messages to a database and restoring them.
