Recognize recipes containing themself

What problem are you trying to solve?

I accidentally included a recipe in itself. The StackoverflowError should be avoided, and a clear error message should be presented.

Describe the solution you'd like

Check any nested recipe to not be in the "already seen" set at the beginning of the initialization request.

Are you interested in contributing this feature to OpenRewrite?

Yes.

Start with DeclarativeRecipe.initialize, especially the locations shown at lines 91, 96, and 106 in the stack trace, and trace how nested recipes are initialized. Use the self-referencing YAML example to verify that initialization detects the cycle and reports a clear error instead of producing a StackOverflowError.
