re-enable allfollow.

[vic]

Now that allfollow is deterministic we no longer have to use jq to sort its output.

We now use delta instead of difftasitc to fail if flake.lock was not already pruned.

I'm not sure now that we need an allfollow check command, since it is better for users to see a nice diff as error message.

Pull Request Overview

This PR re-enables the allfollow tool by uncommenting previously disabled commands and updating the diff tool from difftastic to delta. The changes leverage the fact that allfollow is now deterministic, eliminating the need for jq to sort its output.

• Re-enables allfollow apply and allfollow check commands that were previously commented out
• Replaces difftastic with delta for diff operations and removes jq dependency
• Simplifies the allfollow workflow by using --in-place flag for pruning operations
