`web-server/src/preprocess/keypoint-codec.ts` 是契约 websocket-keypoints §2 的
**参考实现**（其 encodeBinaryFrame 注释即「Android 端参考实现」，
decodeBinaryFrame 注释即「Windows 端参考实现（T-WIN-004）」）。Android 已用
「金标准字节向量」与它对齐，而 **Windows 的 GDScript 解码器此前只跟自己比过**
（自己编码、自己解码）—— 那条边由本仓暴露出的向量来补。
新增：
* scripts/gen-frame-vectors.mts（+ npm run vectors:frame）：用参考实现生成 12 个
用例的字节与**参考解码结果**，供 Windows 仓的 accept-frame-vectors.sh 锁定比对。
向量里同时给出 inputPoints（原始 float64 输入）、f32InputPoints / f32Hex
（收敛到 float32 的**同输入**基准）与 points（参考解码结果），各自注明用途。
* test/keypoint-frame-codec.spec.ts（7 项）：把参考实现对其他两端的承诺显式钉住 ——
i16 最小值边界（-32768/32767 必须是 0x8000，不能被夹成 -32767）、
**取整规则**（JS Math.round 半数朝 +∞：-2.5 → -2，与 Android 的 Math.round 一致）、
置信度阈值 128/255 与两端夹紧、u32 frame_id（0xFFFFFFFF / 0x80000000）、
flags 只取低 8 位、非法帧（长度 / magic / 版本）拒绝、20 组随机输入的往返量化误差。
实测：npm run verify 全绿 —— 契约 6 项 / 35 路由 / 版本一致 / 26 文件 302 项测试
（原 295）/ build / 产物级实体注册核对 / 启动冒烟。
