Resolve the nested class hyde- directive inheritance issue

nested classes within a class don't "see" their parent class hyde directives. e.g., `@hyde-owner` at the parent class level does not propagate down into the nested class. This needs to be resolved.

No files, tests, or entry points are named. Start by locating handling for nested classes and hyde directives, then compare parent and nested-class behavior; done means directives such as @hyde-owner propagate from a parent class to its nested classes.
