[architecture] Long conversation transcripts anchor the LLM on irrelevant early turns

Implement rolling context summarization. Once the context exceeds a threshold \(e.g., 70% of token limit\), summarize the oldest turns into a compact 'session state' block, keeping only the last N turns raw.

Journey Context:
LLMs suffer from recency bias and lost-in-the-middle attention failures. A massive raw transcript dilutes the attention paid to the system instructions and the most recent user query. The tradeoff is the compute cost of summarization vs. the degradation of reasoning. Summarizing the prefix preserves the narrative arc without the token bloat, stopping old context from polluting new answers.
