feat: detect all package changes

[SMillerDev]

This should allow us to use this flow in homebrew/cask too.

[MikeMcQuaid]

Looks good so far!

I guess it feels a little half-way for now; I'd probably rather it either moves to entirely moving things over to packages or having separate formulae/casks for variables and flags. There's probably always going to warrant a need for some different classes for Formulae*/Casks*

[SMillerDev]

Doesn't every tap use this function by default? That would be a lot of people who suddenly have their tap broken if we remove the formulae_ variables.

I'm fine splitting up the variables and/or making a combination. But just to make sure: you're only talking about this method right? You're not looking for me to add casks to all flags in this PR.

It does but we can/should change that in Homebrew/brew and add a deprecation.

I think it's fine to have for now but I guess I'm a little confused as to how it ends up being useful when only detection is done and nothing else?

[SMillerDev]

Since detection is a separate step, it allows me to move another part of cask CI to testbot.

Everything after that will take more work so I'd like to do them separately

Ok, makes sense. If it's useful as-is: great.

Updated to be specific to casks.

Great work, thanks @SMillerDev!

[MikeMcQuaid]

Good to 🚢 when CI is 🟢

[SMillerDev]

I have no clue why CI could be failing, as far as I can tell it should be bright green

[MikeMcQuaid]

Invalid usage: Did not find any formulae or commits to test!

Looks like CI is perhaps legitimately broken.
