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）
