v0.4.20 — Connect 待播队列 / Connect queue

修复：通过 Spotify Connect 播放时，「下一首播放」「添加到待播清单」真正排进队列。

• 之前右键选「下一首播放」或「添加到待播清单」会提示成功，但歌没有进播放列表，下一首仍按原歌单顺序播放：Connect 下队列由 Spotify 掌握，本地加的歌被下一次同步覆盖了。现在这两个操作会发给正在播放的设备，排进 Spotify 的待播队列；已有手动排队的歌时排在它们后面。Connect 正在重连或操作排满时，也不再误报「将在下一首播放」。感谢 @denovochen（#18）。

English

Fix: Play Next and Add to Queue now really queue the song while playing through Spotify Connect.

• Through Connect, Spotify holds the queue, so a song added only to MySpotify's own queue was dropped at the next sync and never played, though the menu said it was queued. Both actions now ask the playing device to add the song to Spotify's queue, after any songs already queued by hand. While Connect reconnects or is busy, the menu no longer claims the song was queued. Thanks @denovochen (#18).

实验平台 / Experimental platforms

• Intel Mac：包内声明最低 macOS 12.0；已有用户反馈可在 Intel 机器上启动和登录，音乐 / MV 播放和实际更新仍待验证。macOS app 未经过 Apple 公证，首次启动如被拦下，可在系统「隐私与安全性」中允许打开。
• Linux：继续使用共享 Qt WebEngine 后端，需另装 Qt 运行时和官方 Chrome 的 Widevine 组件。以运行 MySpotify 的普通桌面用户执行附件 install-linux-webview.sh。依赖和验收范围见 Linux 说明。
• Intel Mac builds declare macOS 12.0 as their minimum. A user has reported that they start and sign in on Intel hardware; music / MV playback and actual updates still need verification. macOS apps are not notarized by Apple; allow the first launch in Privacy & Security if blocked.
• Linux continues to use the shared Qt WebEngine backend and needs a separate Qt runtime plus Widevine from official Chrome. Run the attached install-linux-webview.sh as your normal desktop user. See the Linux guide for dependencies and verification limits.
