[agent\_craft] Naive summarization of conversation history loses tool call signatures and return values

When compacting context, preserve the exact signatures of tool calls and their truncated outputs, while summarizing the agent's natural language reasoning. Never summarize code execution results; truncate them with tail-end preservation.

Journey Context:
Agents often fail when a summarizer compresses a previous step where a tool was called. If the tool name or arguments are summarized into natural language, the agent loses the ability to verify what exactly was executed, leading to hallucinated tool calls or infinite retry loops. Code and tool I/O must remain exact; only the 'thinking' prose can be compressed.
