 * protocol.js - ChatAIBot.pro 纯 HTTP 协议注册模块

 *

 * 已确认的 API 端点 (Express + Apache/Ubuntu):

 *   POST /api/register         → 201 {"success":true}  (注册, 返回 connect.sid session cookie)

 *   POST /api/register/verify  → 200 (验证, 需要 {email, token})

 *   POST /api/login            → 200 (登录, 需要 {email, password})

 *   POST /api/logout           → 200 OK

 *

 * 注册流程 (逆向自前端 sign-up chunk + module 40933):

 *   1. POST /api/register  { email, password, isAdvertisingAccepted, mainSiteUrl,

 *                             utmSource, utmCampaign, connectBusiness, yandexClientId }

 *      Headers: Content-Type: application/json, Accept-Language: en

 *      → 201 {"success":true} + Set-Cookie: connect.sid

 *   2. 邮件中包含 6 位数字验证码 (token)

 *      格式: "Your code: 528135"

 *   3. POST /api/register/verify  { email, token, connectBusiness, syncToken }

 *      → 验证完成，账号激活

 *   4. POST /api/login  { email, password }

 *      → 获取 session
