fix: properly handle @libsql/client native dependencies for Vercel deployment

- Mark @libsql/client as external in esbuild (cannot bundle native bindings)
- Copy entire @libsql scope to include platform-specific binaries
- Add @libsql to vercel.json includeFiles pattern

Fixes "Cannot find module '@libsql/linux-x64-gnu'" error on Vercel
