当MSD或OTG网络配置变更导致gadget被重建时，新的/dev/hidg*设备 被创建但HID后端因'配置未变'跳过了reload，导致仍持有已删除设备 的旧文件描述符，键鼠操作无效。 修复: 在apply_usb_config中检测gadget是否因MSD/网络变更被重建， 若是且HID后端为OTG，强制reload HID以打开新的/dev/hidg*设备。 同时为MsdConfig添加PartialEq derive以支持变更检测。
- Add UAC1 gadget function (ConfigFS) with optimized endpoint config - Browser mic capture with Opus encoding via WebCodecs AudioEncoder - WebSocket audio transport (Opus 64kbps, 100x bandwidth reduction vs raw PCM) - aplay subprocess for reliable PCM playback to USB gadget - Settings toggle + ActionBar mic button (hidden when UAC disabled) - Dynamic PCM device resolution (/proc/asound) - c_chmask=0 + req_number=4 fixes DWC3 composite isochronous endpoint issue

被创建但HID后端因'配置未变'跳过了reload，导致仍持有已删除设备
的旧文件描述符，键鼠操作无效。
修复: 在apply_usb_config中检测gadget是否因MSD/网络变更被重建，
若是且HID后端为OTG，强制reload HID以打开新的/dev/hidg*设备。
