@sorvell, @justinfagnani - any chance to release a patch version for this ? Potential consequences of the bug can be dire (see #3296 - wich cause one of my app to break when using @lit-lab/context decorators)

* [cli] Lazily install and locally version localize

Also merge the two localize commands into one

They have just about the same deps and share some setup and teardown code, there's no win in putting them in separate modules.

This should print out the stderr output in the case there was some.

* Fix error output

The .finally fork of the Promise.race result promise was causing an early exit from node before the ordinary uvu error handling could kick in.

It was passing locally because the cwd was set to the CLI directory, but we want to run in a fake workspace directory.
