Update the positional argument help.
The Functions help text says that the argument is optional only in a project. It is also optional when the Configuration metadata file supplies Function dependencies. Update the Kong help text to describe both cases.
As per path instructions, “Review CLI commands for proper flag handling, help text, and error messages.”

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Handle non-not-found file errors before fallback.
os.Stat can return permission and I/O errors. The project-file branch treats these errors as a missing project and starts Configuration fallback. The Configuration branch then hides its own access failure with a Functions-argument error.
Only use fallback behavior when os.IsNotExist(err) is true. Return a wrapped access error for every other error. Add coverage for a non-not-found error.

Use the required args and want test structure.
ParseConfiguration covers error cases with expectErr, but the test should compare want.err against the returned error with cmp.Diff and cmpopts.EquateErrors(). ResolveConfigurationFunctions already uses args/want and cmp.Diff, and it has no returned errors, so no error comparison is needed there.

Nit: It would be more efficient to unmarshal only once (into a pkgmetav1.Configuration) and then check the GVK (the rest of the object might be garbage if the GVK is wrong, but we'll throw it away anyway). Any downside to doing that?

We also need to handle the modern dependency style that uses APIVersion, Kind, and Package. No objection to handling both - lots of people are still using the deprecated style.
