 *
 * 最小验证: 真 claude CLI 跑一次 PM Agent,看 ClaudeCliProtocol +
 * --append-system-prompt + 工作树 mtime diff 这条 real 链路是否
 * 端到端能用。预算 $0.50 cap。
 *
 * 期望:
 *   ① claude 进程 spawn 成功
 *   ② Agent 输出非空 (result_text 有内容)
 *   ③ files_written 至少 ≥ 1 (Agent 调用 Write 工具写了文件)
 *   ④ git 有新 commit
 *
 * NOTE: 真 LLM 输出不可控;PM 可能不完全照 prompt.md 跑全套 11 章节。
 *      只要它写了任意 prd/* 文件就算 wire-up 通。
