Hi @atu-record ,
I tested your branch locally, and it works great with Svelte 5, both using +page.ts and a server-side approach via +page.server.ts. Amazing job 🚀
This could serve as a solid foundation for the new major version of Storyblok Svelte (version 5).

In any case, based on my tests, the latest version of Storyblok Svelte appears to be compatible with Svelte 5. Did you encounter any issues? I mention this to identify a proper level of priority for the release of a new major version of Storyblok Svelte. (useful for @edodusi )

hi @roberto-butti,
when i updated the repo everything worked like a charm with @storyblok/js@3.1.9
the only issue I briefly encountered was with version https://publint.dev/@storyblok/js@3.2.0
as the package.json threw an error while importing. 3.2.1 works flawless again.
if I encounter anything during our projects I will come back to you. If you need anything else let me know.

Thank you @atu-record for your work and @roberto-butti for your review, I will look into this ASAP with the goal of crafting a new release fully supporting Svelte 5 🚀
