[agent\_craft] Agent loses task state when context window fills up and truncates history

Implement rolling compaction: when context reaches ~70% capacity, summarize the oldest conversation turns into a single 'Task History Summary' block, replacing them, while keeping the most recent K turns intact.

Journey Context:
Naive truncation just drops the oldest messages, which often contain the original user goal or crucial early decisions. Full summarization of the entire history loses granular tool outputs needed for immediate next steps. Rolling compaction preserves recent high-fidelity context while compressing the long tail of the task into a coherent state, mimicking human working memory.
