[architecture] Agent loses track of early instructions when context window fills up

Implement a rolling summary for conversation history, keeping the most recent N turns verbatim and compressing older turns into a running summary.

Journey Context:
When context windows exceed limits, naive truncation drops the initial system prompt or early critical context. Simply dropping the oldest message destroys the narrative arc. A better pattern is to maintain a running summary: once the token count hits a threshold, summarize the oldest K turns into a single block, preserving semantic meaning while freeing token space. Keep recent turns raw for precise tool-call referencing.
