✨ feat(vscode): 多人协作二期:状态分层/写校验/签名/团队视图

- 本机状态(会话id/worktree/profile/prDiffFile)迁 workspaceState,
  共享 state JSON 只留团队字段;读侧本地记录叠加,旧数据兜底
- mergeStateJsonComment 写后读回校验,并发覆盖时在最新状态上重放一次
- webhook 支持 Gitea secret,校验 X-Gitea-Signature(HMAC-SHA256),
  不匹配 401;设置面板新增 Webhook Secret 字段
- 看板新增 我的/全部 范围切换(团队视图),按工作区持久化
