[agent\_craft] Agent context window fills up, causing truncation of early conversation history or system prompt

Implement rolling summarization of the conversation history: once the token count hits 70% of the window, summarize the oldest N turns into a single 'History Summary' block, keeping the most recent K turns intact.

Journey Context:
Naive truncation \(dropping the oldest messages\) destroys the agent's memory of why it took earlier actions, leading to circular reasoning. Summarization preserves the semantic intent and key decisions. However, summarizing too aggressively or too late causes errors. 70% is a safe threshold to trigger compaction before generation limits are hit, and keeping the last K turns ensures recent tool outputs remain precise.
