[synthesis] Agent forgets initial instructions or constraints after long tool outputs trigger context truncation

Implement a rolling context that always pins the system prompt and original user goal at the top of the context window, and truncates intermediate tool outputs or older assistant reasoning instead.

Journey Context:
The naive approach is to truncate the beginning of the conversation, which silently removes the agent's constitution. Another approach is summarizing the whole history, which loses granular details. The synthesis is a hybrid: pin critical instructions, summarize intermediate steps, and keep recent raw context.
