Major Svelte version bump breaks incompatible companion dependencies

High Severity

Bumping svelte from 3.59.2 to 5.55.7 without updating companion devDependencies creates an incompatible dependency set. @sveltejs/vite-plugin-svelte 1.4.0 only supports Svelte 3 (needs v5+ for Svelte 5), and @testing-library/svelte ^3.2.1 doesn't support Svelte 5 (needs v5+). This will break the test infrastructure entirely — vitest won't be able to compile Svelte components, and component rendering/interaction tests using $set() will fail.
