9b72cdb8f0The complete migration from `minecraft-assets` to [`mc-assets`](https://npmjs.com/mc-assets). Now all block states & block models are processed dynamically! So it is now easily possible to implement custom models - no post-install work anymore: the building is now 3x faster and 4x faster in docker - drop 10x total deploy size - display world ~1.5x faster - fix snow & repeater state parser (they didn't render correctly) rsbuild pipeline! - the initial app load is faster ~1.2 - much fewer requests are made & cached - dev reloads are fast now Resource pack changes: - now textures are reloaded much more quickly on the fly - add hotkey to quickly reload textures (for debugging) assigned to F3+T (open dev widget is now assigned to F3+Y) - add a way to disable resource pack instead of uninstalling it - items render from resource pack are now support - resource pack widgets & icons are now supported
