[architecture] Rolling context window summaries losing critical early details

Extract explicit, atomic facts \(e.g., 'User's name is Alice', 'Project deadline is Oct 12'\) into a structured long-term memory store \*before\* summarizing the context window. Use the summary only for conversational flow, not as the source of truth for hard facts.

Journey Context:
To manage context limits, agents often summarize the conversation history. However, LLM summarization is lossy and tends to drop specific numbers, names, and edge-case constraints in favor of high-level themes. When the agent later needs a specific detail, it's gone. The tradeoff is context length vs. fact retention. The solution is a 'memory-first' extraction step: pull out atomic facts into a database, then summarize the rest. The summary handles the vibe of the conversation; the database handles the data.
