go.work as a step in the CLI so that it always works and is contained.

[gedw99]

for the examples I have to generate a go.work

this is because I am in a mono repo.

this means that everything works if you are and are NOT inside a mono repo.

so, it seems like a good idea to add this to the cli....

all I do is call "go work use ./examples/todo" etc....

I added it to all cmd steps like gen, run, watch, setup as a pre step.

works well.
