• Removed compile-time dependency on the cardano-addresses-cli, runtime dependency is taken from a flake input.

Excellent, thank you! 👍 😊

I would suggest to pin optparse-applicative in the cabal.project in order to facilitate an eventual switch, but I'm not sure if that works here. Worth a try, though.

It looks like we're able to bump the run-time dependency on cardano-node to v 8.1.2 without having to update other dependencies: #4302 .

This pull request should be re-envisioned as a dependency update. For this purpose, I would like to:

• Decouple an update of the Hackage index (potential build plans) from an update of the dependencies proper (actual build plan). This requires specifying version bounds and additional constraints on our part.
• Since cardano-addresses is currently unmaintained, we will have to deal with this dependency separately.
