Same options as in packages/react-devtools-extensions/webpack.config.js. I'll merge these two configs once they're similar enough.

Seems like a mistake. react-devtools-extensions/webpack.config.js doesn't define that var either.

When we disabled minification for the backend in #19369, we didn't have sourcemaps. As of #28730 we do so we can minify it again.
Minification isn't just about reducing parsed size but also about reducing runtime overhead via various compiler optimizations. We only use Terser at the moment but should use Closure in the future.
