Update to latest version of SvelteKit

Editor assessment

The subject states that the web app was updated to the latest version of SvelteKit, which records the intent but not the fact: no version number appears anywhere, so the message cannot tell a reader what upgrade actually landed or which breaking changes accompanied it. The feat type is a loose fit for a dependency upgrade, and the web scope is meaningful. No body exists to supply the version or the migration notes, and no footers appear. Hygiene is clean. Understandable in direction, but unversioned upgrade messages age poorly and inform weakly.
