Fix Vercel deploy error - mark @libsql/client as external

- @libsql/client has platform-specific native binaries (@libsql/linux-x64-gnu)
- Cannot be bundled - must be kept external and copied from pnpm virtual store
- Update build-vercel.sh to copy @libsql scope from node_modules/.pnpm/node_modules
- Update vercel.json includeFiles to include @libsql scope
- Also fix @ai-sdk copy to use pnpm virtual store path
