When ReplaceLambdaWithMethodReference converted an unbound instance reference like s -> s.method(), it built the class name from the method's declaring type. If that type was package-private and the receiver was a public subclass in another package, the result (e.g. Base::getValue) failed to compile because the declaring class could not be imported.

This change uses the receiver/select type to construct the class name for unbound instance method references, falling back to the declaring type only when the select type is not a fully-qualified type. Static method references continue to use the declaring type unchanged.

Added a regression test reproducing the three-file scenario from the issue.

…mbdaWithMethodReference`

Previously the recipe used the method's declaring type to construct
the class name, which produced uncompilable references like
`Base::getValue` (with an inaccessible import) when the declaring
class was package-private and the receiver was a public subclass.
