npm ci with a Windows-generated lockfile skips @libsql/linux-x64-musl
(optional native dep). Switching to npm install lets npm resolve the
correct platform-specific binary for the Alpine container. Also copy
node_modules into the runner stage so prisma db push and the libsql
native module are available at runtime.
