[architecture] Hard truncating the oldest messages to fit the context window limit

Use a rolling summary mechanism that continuously summarizes the oldest messages into a single system-level summary block, preserving high-level context while discarding token-heavy conversational details.

Journey Context:
Hard truncation is catastrophic for agents. It silently drops early system prompts, few-shot examples, or critical instructions established at the beginning of the session. A rolling summary compresses the historical timeline into a compact state, maintaining the narrative thread and preserving early constraints without blowing the context budget.
