remove sourcemap url

Hi @tjx666, thanks for the issue. The sourceMappingURL comment is autogenerated by rollup and helps navigate to the source map file and finally to the original source code during debugging. I believe this comment is generated by rollup because of sourcemap: true in rollup.config.js.

You should set sourcemap: false when build for production, or it will cause debugger tools issue because you declare the sourceMappingURL but not actually exists;

instead, I think we should publish the sourcemap files, for better debugging.

We don't actually need the source files for debugging as the source is in ESM already. We should just remove sourcemap:true from rollup.config.js.

@nzakas was this intentionally labeled as a breaking change?

Oops! No. I meant to label as "bug". Thanks for catching that.
