This allows a user to choose private or public visibility on `rad init`.
It also improves the output to tell the user what happened due to this
choice.
It didn't make sense to get eg. `Patch failed` when listing patches
failed. We change all fatal errors to simply "Error:", giving more
control over the individual commands.
When a fetch is user-requested, a timeout can be supplied that is passed
down to the worker.
When a fetch is service-requested, a default timeout is used.
