[architecture] How to persist agent state across sessions without overloading the new session context

At session end, generate a structured 'session summary' containing only the current state, unresolved goals, and key entities. Store the summary as the primary cross-session memory artifact, not the raw transcript.

Journey Context:
Developers often try to pass the entire previous session's context window into the new session. This quickly hits token limits and carries forward resolved issues and dead-ends, confusing the LLM. The alternative is starting blank, which loses state. The right pattern is a summarization step at session termination. The tradeoff is the cost of an LLM call at session end vs. a clean, highly relevant, low-token starting state for the next session.
