Hey @N1ebieski! 👋

I hope you don't mind that I opened a new PR to take a slightly different approach on this. Your original PR really helped highlight what needed to change!

I ended up moving most of the logic directly to the PHP template side. This allows us to correctly filter and format Livewire 4 components at the source, which keeps the extension-side changes minimal and strictly preserves backwards compatibility.

I also feel this approach gives us a better path forward to eventually separate Blade and Livewire features for deeper support down the road.

Thanks again for kicking this off! 🚀
