Use BundleWatch to monitor bundle size

[bradenmacdonald]

Per OEP-67, this PR configures the repo to use BundleWatch.

I'm not sure if I have permission to enable their app / full GitHub integration, but for now this will at least raise an error during CI if any of the bundle fragments are larger than a certain size.

I wish there were a way to limit the total bundle size as well, but that seems not to be the case.
