Major version bump breaks incompatible companion dev dependencies

High Severity

Bumping svelte from 3.59.2 to 5.53.5 without updating companion dev dependencies breaks builds and tests. @sveltejs/vite-plugin-svelte at 1.4.0 was built for Svelte 3 (depends on svelte-hmr@^0.15.1) and is incompatible with Svelte 5's completely rewritten compiler and runtime. @testing-library/svelte at ^3.2.1 uses Svelte 3/4 component instantiation APIs (new Component()) that no longer exist in Svelte 5 — version 5.x of this library is needed. Tests also use component.$set() which was removed in Svelte 5. The vite config alias mapping svelte to svelte/internal is broken since svelte/internal no longer exists in Svelte 5 (replaced by svelte/internal/client).
