Thanks for the fix, @BigGold1310! The core of the change looks good to me. I've left a few suggestions to clean up the implementation a bit (in particular, avoid duplicating the XRD-to-CRD conversion logic we have elsewhere).

Could this test become a case and additional validation steps in the existing TestManager_AddPackage?

I think it's sufficient to test this just in the dependency manager. The project builder is a layer removed.

This largely duplicates the createCRDFromXRD helper from the internal/crd package. That helper seems generally useful enough that it could be exported as something like crd.FromXRD(). Then the only unique part here is the file naming, which makes sense to stay next to CRDFilesystem.

The createCRDFromXRD method is now exported as FromXRD and used by my implementation.

Make the XRD conversion error actionable.
When package schema generation reaches this error, it describes an internal CRD derivation step but gives no recovery action. State that the XRD schema must be validated and corrected before retrying. Apply the same guidance to the claim CRD error path.
As per path instructions, error messages must give user context and suggest next steps when possible.

Group test inputs and expectations in args and want.
Thanks for adding XRD coverage. body and generators are inputs, while wantKey and wantSchemaGlob are expected results. Group them in args and want, and add reason to each case for assertion output.
As per path instructions, **/*_test.go requires an args/want pattern and reason fields.

Description of your changes
If you added a Configuration-type dependency (one that bundles XRDs) with crossplane dependency add or update-cache, it would quietly generate no schemas at all — no error, just nothing. crossplane project build had the same bug, since it uses the same code underneath.
The problem: the code that pulls CRDs out of a package only knew how to handle plain CRDs. When it ran into an XRD instead, it just skipped it silently.
The fix: teach that code to also recognize XRDs and convert them into the CRDs Crossplane normally generates from them (the composite resource, plus the claim if there is one). This reuses the conversion logic Crossplane already has elsewhere, instead of writing new logic from scratch. Regular CRD-based packages (Providers) work exactly as before.
Added tests that check real schemas actually get generated for XRD-based packages — for dependency add, and for project build.
