nit: If we're passing in a specific arg, it could be a nice hint to the reader to identify the arg via an explicit parameter for packagesExec, rather than receive the whole slice and grab item 0 just in time.

Just double-checking that this was intended, since I couldn't remember if we're adding new ANSI logic here.

I've used this package before and decided to use it for the hide/show of the cursor (was intended)

Just curious: What is "●" for?

I can remove this --it was used during early development when I was flopping between options

Today the event loop is coupled with the specific UI details, which is not ideal. This PR splits out those concerns, migrating the event loop from the
uipackage tocmdand extracting theui.UIfunction into an interface for setting up a UI, handling individual events from the event loop, and tearing down the UI. This allows for flow control, signal handling, and worker/event management to be shared, and the UI specifics to be implemented behind an interface --this allows for the ability to swap out the ETUI implementation for the logger implementation, but now without duplicating flow control logic.Closes #416
