Report #15808

[architecture] Agent's context window fills up with historical conversation, causing it to drop the system prompt or recent instructions

Implement rolling context window management: summarize the oldest N turns of the conversation and replace them with a compact summary token block, preserving the system prompt and recent turns verbatim.

Journey Context:
As context length grows, attention dilutes and inference costs spike. Simply truncating history loses information. Summarization compresses the tail of the conversation, maintaining continuity without exhausting the context budget. This prevents the agent from 'forgetting' its core directives.
