Credential Management API：密码凭据存储与自动填充

概述Credential Management 提供统一的凭据接口，支持获取与存储密码凭据。与自动填充协作可减少输入与提升登录体验。用法/示例const cred = await navigator.credentials.get({ password: true }) if (cred) { const r = await fetch('/login', { method: 'POST', body: new URLSearchParams({ id: cred.id, password: cred.password }) }) } const stored = new PasswordCredential({ id: '[email protected]', name: 'User', password: 'pass' }) await navigator.credentials.store(stored) 工程建议在安全上下文中使用并最小化敏感数据的前端存储。对不支持环境使用传统表单与密码管理器回退。与服务器端会话与风险控制协作，防护暴力与滥用。参考与验证MDN：Credential Management — https://developer.mozilla.org/docs/Web/API/Credential_Management_API
