🐛 fix: resolve CI/CD build failures for manacore-web and todo-web

- Replace lucide-svelte with @lucide/svelte (Svelte 5 runes compatible)
- Add shared-splitscreen and shared-types to todo-web Dockerfile
- Update pnpm-lock.yaml with new dependencies

The old lucide-svelte package used $$props (Svelte 4 syntax) which
fails in Svelte 5 runes mode. The new @lucide/svelte package is
built specifically for Svelte 5.
