 * DevLoop P0 末端验收检查器(不发起任何子进程,只做静态校验)。
 *
 * Checkpoints:
 *  [1] 35 个 devloop 工具全部 loadable
 *  [2] 6 个 devloop-* agent 在 system/templates/_registry.json 注册
 *  [3] 每个 devloop-* 目录有 prompt.md + config.json (含 cli.toolPolicy)
 *  [4] bash-json-guard 可挂在 Bash preExecute (顶层 index.js 暴露)
 *  [5] services/devloop 7 大件 + tool layer 7 大件 全部 require 成功
 *  [6] mock fixtures 默认+pm 两个文件存在
 *  [7] git-vault + path-resolver 接口存在
 *
 * 通过即 exit 0,任一失败 exit 1。
