Report #11305

[architecture] Agent leaks context from previous unrelated sessions

Namespace memories by session ID and user ID. When starting a new session, load only a high-level summary of past sessions, not the raw episodic memories, unless explicitly requested.

Journey Context:
Storing all user memories in one flat collection causes cross-contamination. If the user was coding a Python script yesterday and a Rust script today, retrieving yesterday's Python snippets might confuse the LLM into writing Python code for the Rust task. Episodic boundaries \(sessions\) must be respected. Summaries act as a safe, abstracted bridge between sessions, preventing low-level context bleed while preserving high-level user preferences.
