// bin/auditstate.mjs — 增量审查状态
//   node bin/auditstate.mjs status            列出「内容变了待复核 / 从未复核 / 已复核未变」
//   node bin/auditstate.mjs update <技能...>   回填复核记录（写入当前 hash + 日期）
//   node bin/auditstate.mjs update --all      全部标记为已复核（仅用于机制初始化）
//
// 审查波工作流：status → 只审列出的技能 → update。成本从 O(技能总数) 降到 O(变更数)。
