chore(deps): raise package.json lower bounds to patched versions

Bumps declared semver ranges to the patched minimums so a fresh
npm install (without the lockfile) cannot resolve to a vulnerable
version:
  @sveltejs/adapter-node  ^5.4.0  →  ^5.5.4
  @sveltejs/kit           ^2.48.5 →  ^2.60.1
  vite                    ^7.2.2  →  ^7.3.3
