* Update builder to use a shared validation method
* Add the error for using print_metadata and watching
We cannot use print_metadata with watching
because print_metadata only makes sense
in build scripts, but watching does not
and would instead stall the script
* Add the initial implementation of watching
* Make hot reloading work in the wgpu example
* Attempt to address CI failures
* Add exception for notify CC0-1.0 license
* Address review comments
