feat(V0.2): 版本方案落地 —— 前端/外壳解绑, build 标识统一, 外壳版本展示

- check-version: 分组校验 (前端 package.json / 外壳 tauri.conf+Cargo),
  两组不再要求相等; 分支前缀校验只针对前端版本
- build-ota: build_id 改为 YYYYMMDDHHmmss (北京时间, 与前端 BUILD_ID
  同格式); sequence 保持毫秒仅用于判新
- 我的页: 当前版本恢复 v0.2.0 · build <原始BUILD_ID>; 新版本附 OTA
  build_id; 底部替换为外壳版本 (Tauri getVersion, Web 端 —)
- README: 合并遗留 readme 全部内容并按决议重写版本管理章节;
  新增 CHANGELOG.md (PATCH 仅明确提出时自增)
