[architecture] Agent loses user context and learned preferences when a new session starts

Decouple user identity from session ID. Implement a User Profile memory store keyed by user\_id, and inject the profile summary into the system prompt at the start of every new session.

Journey Context:
Chat APIs are stateless. Session history is often tied to a single thread, meaning new threads start with amnesia. To achieve cross-session persistence, you must separate 'thread memory' \(what happened in this specific chat\) from 'user memory' \(who this person is\). When a session starts, fetch the user memory, populate the system prompt, and at the end of the session \(or asynchronously\), update the user memory with new facts.
