dsh-dream-skin: DSH Web Native Token Skin and Theme Pack

dsh-dream-skin is a DSH standard dual-face skin-swapping plugin maintained by RevolutionLA. It natively registers 8 sets of Mirage preset skins through ctx.theme, supporting Wallpaper 2.0, per-user accent colors, theme package import/export and share links, as well as favorites and random switching. The installation command is `dsh plugin --profile web add dsh-dream-skin`, and configuration can be done in Settings → Appearance after restarting DSH Web. Licensed under MIT, it does not inject or modify the installation package, making it suitable for DSH Web users who prefer a restrained and elegant interface.
