/**
|
||||
* BrainyChat - Magical Chat Command Center
|
||||
*
|
||||
* A smart chat system that leverages Brainy's standard noun/verb types
|
||||
* to create intelligent, persistent conversations with automatic context loading.
|
||||
*
|
||||
* Key Features:
|
||||
* - Uses standard NounType.Message for all chat messages
|
||||
* - Employs VerbType.Communicates and VerbType.Precedes for conversation flow
|
||||
* - Auto-discovery of previous sessions using Brainy's search capabilities
|
||||
* - Hybrid architecture: basic chat (open source) + premium memory sync
