[architecture] Repeatedly summarizing conversation history leading to catastrophic loss of specific details and hallucinated state

Maintain a rolling buffer of exact recent interactions alongside a slowly updating semantic summary, rather than summarizing the whole context repeatedly.

Journey Context:
A common pattern to save space is to summarize the context whenever it gets full. If you summarize a summary, you compound errors and lose granular details \(like specific variable names, IDs, or exact error messages\). Instead, keep the last N turns verbatim in a buffer, and only summarize the older history. This preserves immediate accuracy for the current task while keeping the context window bounded.
