Subject: fix(vad): bundle local Silero model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[问题原因]
- 先前实现会在包内权重缺失时读取外部 faster-whisper 资源，无法满足自包含部署要求。

[问题根因]
- 项目包中尚未包含已验证的 ONNX 权重，VAD 路径保留了开发期回退逻辑。

[修复方案]
- 提交已校验 SHA-256 的本地 Silero ONNX 权重并移除外部包回退。
- 增加模型打包和缺失模型失败路径测试，并更新来源、MIT 许可和哈希说明。

[影响范围]
- VAD 现在只加载项目包内模型，不联网且不依赖 faster-whisper 运行时资源。
- 未安装、启用或启动任何用户 systemd 服务。
