feat: Unified Ingest SDK for DMS/ADAS promote, cuboid export and 3D fit

Replace subprocess build with promote_batch SDK, add ADAS cuboid export/fit/validate pipeline, stage normalization, and offline unit tests wired into smoke_labeling_api.

+
+## 管线
+
+1. **labeling_export** — CVAT ls_annotations → `labels/quaternion_json/*.json`
+2. **cuboid_fit_3d**（有 calib 时自动触发）— 补全 3D 字段
+3. **build_adas**（审核）— `promote_batch` 复制到 pack + 刷新 stem 列表
+
+## CLI
+
+```bash
+# 导出（平台 Job 或脚本）
+PYTHONPATH=platform python3 -c "from as_platform.labeling.export_cuboid_batch import export_batch; ..."
+
+# 3D 拟合
+PYTHONPATH=platform python3 -c "from as_platform.labeling.fit_cuboid_batch import fit_batch; ..."
+
+# 入包
+python as.py build adas cuboid_7cls --batch val_front6mm_pilot --pack adas_moon3d_v1
+```
+
+## Smoke
+
+```bash
+bash scripts/smoke_adas_promote.sh
