KeyBridge / 键桥 1.5

接收组件安装／更新后，自动局部重新加载键桥的虚拟麦克风，取消默认要求重启电脑的流程。
不终止整个系统音频服务或其他音频驱动。管理员确认仍由系统安装器处理；键桥虚拟麦克风可能短暂中断。
已在 Mac mini、macOS 15.8.1 上确认：键桥驱动宿主更换，主 coreaudiod 与其他音频组件 PID 不变，新驱动实际加载。组件恢复不等于语音应用已完成收音验收。
修复 Fn 接收事件类型遗漏，增加 Fn／扩展功能键／系统按键的原生事件通道，保留按下、松开和长按的原始事件类型与标志，不映射成应用快捷键。两端需更新；F5 听写和微信 Fn 长按的实际行为仍待用户确认。
保留单个麦克风勾选项：缺少组件时引导安装，准备完成后自动继续，采集与接收都就绪才显示开启。
已正常加载 1.4 接收组件的用户无需再次安装组件；应用更新即可。默认关闭、有线限定、断线停止及不自动恢复录音保持不变。

English

Receiver installation/update reloads only KeyBridge's isolated virtual-microphone helper; no computer restart is requested.
The installer does not terminate coreaudiod or other audio drivers. Administrator approval stays in the system installer, and KeyBridge's virtual input may briefly disappear.
Scoped reload was observed on the target Mac mini with macOS 15.8.1: KeyBridge helper replaced, other audio PIDs unchanged, new component loaded. Voice-app audio acceptance remains separate.
Adds a negotiated native-keyboard path for Fn, extended function keys and system-defined auxiliary keys, preserving original event types and flags rather than mapping application actions. Physical F5/WeChat acceptance is pending.
Setup continues automatically after component readiness. Both microphone switches turn on only after capture and reception are ready.
An already loaded 1.4 receiver implementation is compatible; reinstalling that component is unnecessary. Wired audio only, default off, no automatic capture after reconnect.
