Support launching published apps à la `cs launch`

Is your feature request related to a problem? Please describe.

A way to run applications published to Maven Central.

Describe the solution you'd like

Essentially if scala-cli could subsume the launch command from coursier. Or something roughly similar.

Describe alternatives you've considered

I could use coursier, but then I need to install two things :) scala-cli is becoming ubiquitous.

Thanks for reporting! This would put ScalaCLI very close to being a package manager. It's something we've been talking and enabling some coursier commands via was an option.

However, currently I would be hesitant to add it as it would make ScalaCLI do a lot of things at the same time. We need to stabilize a bit the current features and maybe come back to this much later.

I have bad news then, I think this has already happened 😛 I realized that I can already accomplish what I want with this command.

scala-cli run . -S 2.13 --dep org.scala-steward::scala-steward-core::0.23.0 --main-class org.scalasteward.core.Main

It's just a bit cumbersome to have to supply the main class and the run . in an empty directory is a bit weird. But maybe this is a just fine workaround.

This is an interesting hack to get the hidden feature 😅 kudos
I think you could get rid of the funny run . by using a snippet with -e.
Something like:

scala-cli -e 'println()' -S 2.13 --dep org.scala-steward::scala-steward-core::0.23.0 --main-class org.scalasteward.core.Main

Also, it seems the main class coming from a coursier dependency isn't properly detected, so we can't view it with --list-main-classes or default to it as is... but that should be fixable, I think.
