- 删除 app/park/vendor/s2s-cloud（201 文件）与 s2s_bridge.py - 清理 app.py/config.py/routers.py/rag.py/tools.py 中 s2s 相关代码与配置 - park_config 智能体提示词配置改名 PARK_AGENT_INSTRUCTIONS（原 S2S_INSTRUCTIONS，仍被园区 AI 问答使用） - pyproject 移除 torch/transformers/scipy/soundfile/nltk/openai（均仅 s2s 使用，Linux 下 torch CUDA 依赖曾致镜像构建下载 4-6GB、耗时 300s+） - 重新生成 uv.lock（移除 torch 等 40+ 传递依赖） - 修复 app/api/schemas/admin.py 缺失 Database import（3.14 延迟注解掩盖的既有 bug，3.12 下启动必崩） - .python-version 同步为 3.12（与镜像一致）
