feat(core): Wave 3.5 前端 — 注册页/登录双态 + 邀请制 API 接线(认证定调:无邮箱)

scaffolding: types.ts 加 Invitation 类型;api.ts 加 listInvitations/createInvitation/revokeInvitation +
  register() 加 invite_code;route-config AuthMode "login"|"register" + /register 返回 register 态;
  App.tsx onModeChange 按 mode 切 /login↔/register URL
auth-screen.tsx(sub-agent):登录+注册双态(按 initialMode 渲染),去掉 /register→/login 强制改写;
  注册表单 = 团队名/用户名/密码/确认密码/邀请码(去邮箱!)+ 左价值点 + 协议勾选 + 一致性校验,
  有码提示「加入团队」无码「开新团队」;登录补第三方(微信/飞书+OR线)+ 切换行 + lead/mono;登录保持秒进
styles.css:仅加 .auth-* 注册态/第三方/切换行 CSS(restraint token)

验证: tsc 0 · build 0 · 走查 登录(无邮箱/第三方×2/切换/秒进698ms)+ 注册(5字段/0邮箱/0「邮箱」文案)
  + 切换态(URL→/register)全过 · 0 console error
