fix(socket): remove bootstrap-smol.js from npm package build

bootstrap-smol.js is built by @socketsecurity/bootstrap and used directly
by the smol+node builder. It should not be built or included in the socket
npm package.

This removes the smol build step from packages/socket, ensuring only
bootstrap.js is included in the npm package.
