[Bug Report]: farm watch doesn't copy /public contents to /dist

[ddorstijn]

Steps to reproduce

Put in any item in the public directory and see that it does get copied over when running farm build but not when running farm watch

Reproduce link

No response

What is actually happening?

I need to have files on disk for my web extension, I have a manifest.json in the public directory. This doesn't get copied over so the extension crashes when using farm watch. Using the farm build -w command does work for now.
