David Peter 58a68f1bbd [ty] Fall back to Divergent for deeply nested specializations (#20988) ... ## Summary Fall back to `C[Divergent]` if we are trying to specialize `C[T]` with a type that itself already contains deeply nested specialized generic classes. This is a way to prevent infinite recursion for cases like `self.x = [self.x]` where type inference for the implicit instance attribute would not converge. closes https://github.com/astral-sh/ty/issues/1383 closes https://github.com/astral-sh/ty/issues/837 ## Test Plan Regression tests.		2025-10-22 14:29:10 +02:00
