tian 29d9ef5d0d refactor: 项目结构梳理 - 设备端/管理端对称布局
仓库结构:
  edge/     设备端(原根目录设备端代码整体移入)
  control/  管理端(清理后)
  docs/     文档(PRD 移入 design/)
  README.md 根导航(新增)

清理:
- control/.brainstorm 临时草稿删除
- control 根级重复文档(API表/PRD_04)并入 docs/design/
- control/plan.md -> docs/implementation/control-plan.md
- control/safesightd-linux-arm64 二进制取消版本控制(.gitignore)
- edge/transform 模型转换产物归入 models/,onnx/pt 大源文件取消跟踪(.gitignore)
- Readme.md(PRD) -> docs/design/PRD_Product_v1.2.md(避开 README 大小写冲突)

更新:
- 根 README.md 导航、docs/README.md 文档索引
- deployment.md/检查表路径加 edge/ 前缀
- .gitignore 重写(edge/control 分区规则)
