WaveMotes

Live emote sync: new server emotes show up on their own, no mod update needed. The mod fetches a manifest the server publishes, caches the new textures and renders them through a resource pack it manages, then reloads resources. The bundled set still renders offline. Toggle in config; /wm sync forces a refresh. Also refreshes the built-in MineWave set to the current 87 emotes. (2.0.1 fixes a startup crash present in 2.0.0.)
