Bug: The application upgrades to Svelte 5 but keeps @sentry/sveltekit at v8.9.2, a version not compatible with Svelte 5's new architecture, which will likely break runtime error tracking.
Severity: HIGH

Suggested Fix

The @sentry/sveltekit package should be upgraded to a version that officially supports Svelte 5. Check the Sentry documentation or release notes for the correct version compatible with Svelte 5 and update the package.json dependency accordingly.

Verify if this is a real issue. If it is, propose a fix; if not, explain why it's not
valid.

Location: apps/sveltekit-2/package.json#L28

Potential issue: The upgrade to Svelte 5 introduces significant architectural changes,
such as components being functions instead of classes and the removal of internal APIs
like `current_component`. The existing `@sentry/sveltekit` version 8.9.2 relies on the
Svelte 4 architecture and its internal APIs. This incompatibility will likely cause the
Sentry integration to fail at runtime. Specifically, the `sentrySvelteKit()` Vite plugin
may fail to instrument components correctly, and client-side error tracking via
`handleErrorWithSentry` may break silently or lose crucial context, defeating the
purpose of the error monitoring.
