feat(recorder): add offline voice clip pipeline
[变更性质] - 本提交新增本机离线的语音片段录音能力,不涉及网络服务或语音识别。 [新增功能] - 通过 Pulse 默认输入持续采集音频,以本地 Silero VAD 触发片段。 - 以私有目录和权限写入 24 kbps Ogg/Opus 录音,并提供 systemd 用户服务安装器。 [实现方案] - 使用有限前置缓冲、静音封段和最长段滚动状态机,避免静音落盘及内存无限增长。 - 增加真实 Opus 编解码、服务 dry-run 和纯逻辑状态转换测试;记录模型归属和部署前置条件。 [影响范围] - 新增 Python CLI、运行时模块、中文运维文档和自动测试。 - 未安装、启用或启动任何用户 systemd 服务;不删除或修改录音数据。
