Report #2368

[architecture] Unbounded context window growth leading to attention degradation and token overflow

Implement rolling summarization \(compaction\) for older context, retaining the summary and a sliding window of exact recent turns.

Journey Context:
Just truncating old messages loses critical state. Just keeping all messages hits token limits and degrades LLM attention \(the 'lost in the middle' phenomenon\). Rolling summarization compresses historical context while preserving semantic continuity, ensuring the agent remembers the 'what' even if it loses the exact 'how' of older steps.
