Support watching go:embed files in encore.run

[Minivera]

The notify.Watch call during the execution of encore.run is configured to only watch go files and the files that encore need to compile the go application,

encore/cli/daemon/run/watch.go

Line 55 in 628ce4e

case ".go", ".sql", ".mod", ".sum", ".app":

If embedding files into the binary with go:embed for example, encore will not recompile when those file change unless you make changes to the go files directly. It would be great if Encore could detect the files I embed in my code and rebuild when those changes, like with JavaScript files for examples.
