 贡献模式的目标不是新增一个 provider，而是在 sidepanel 内开启一套“贡献账号”专用 UI，并把公开贡献服务并进原有 10 步主链：
 
 1. 用户点击顶部 `贡献`
-2. sidepanel 复用现有 `openConfirmModal(...)` 打开确认弹窗
-3. 用户确认后，后台通过 `SET_CONTRIBUTION_MODE` 切换运行态
-4. 进入贡献模式后会强制 `panelMode = cpa`，并临时清空运行态 `customPassword`、禁用运行态账号记录快照同步
-5. sidepanel 隐藏 CPA 管理地址、管理密钥、SUB2API 配置、自定义密码、本地同步等普通模式配置，并禁用来源选择、配置菜单和记录入口
-6. 用户点击 `开始贡献` 后，不再单独走一条旁路 OAuth 流程，而是直接复用顶部 `自动` 的同一套主自动流
-7. 步骤 1~6 仍按原来的注册自动化执行
-8. 当主流程进入步骤 7 时，后台改为调用公开接口 `POST https://apikey.qzz.io/oauth/api/start` 申请贡献登录地址，而不是去 CPA / SUB2API 面板刷新 OAuth
-9. 步骤 7 拿到 `session_id / auth_url / state` 后，继续沿用原有登录链路进入授权页
-10. 步骤 9 仍负责捕获 localhost callback；贡献模式下后台也会持续监听导航变化，必要时提前兼容处理 callback
-11. 步骤 10 在贡献模式下不再打开 CPA 管理页，而是围绕公开贡献会话做 callback 提交兼容和最终状态确认；当状态进入 `auto_approved / auto_rejected / manual_review_required / expired / error` 时结束
-12. 当前服务端如果返回“无需手动提交 callback”，扩展会把它视为兼容成功态，而不是报错
-13. `已有认证文件？前往上传` 继续打开 `https://apikey.qzz.io/`
