fix(apps/demo): add @libsql/client and nanoid as explicit devDependencies for Vercel

workspace:* packages bypass pnpm's .pnpm virtual store, so their
transitive deps are not discovered by patch-symlinks.cjs Phase 1.
Add @libsql/client (^0.17.2) and nanoid (^3.3.11) — runtime deps of
@objectql/driver-turso — as explicit devDependencies so they are
available in node_modules for Vercel bundling.
