//! `list_accounts`:账户清单(**凭据永不出口**)。
//!
//! 这个工具存在的理由很具体:用户常问「我有哪几个号 / 这局用的是哪个号」。
//! 但 D4/D9 的凭据红线是硬的——工具结果会回灌模型、也可能被发往远端 LLM,
//! 所以:
//! 1. 端口只回 [`crate::port::AccountSummary`](`AccountMeta` 的公开字段);
//! 2. 本文件里**没有任何**能表达 token / 密码的类型(连字段名都不出现);
//! 3. 工具结果再过一遍 [`crate::redact`],兜住实现方把凭据塞进 `profile_name` 的意外。
