Typing stubs for retry

The `types-retry` package provides PEP 561 compatible type stubs for the `retry` library (pypi.org/project/retry), enabling static type checking for code that implements retry logic. As an auto-generated part of the `typeshed` project, it receives regular updates to reflect the API of the `retry` library. The current version is 0.9.9.20260408, with releases typically tied to updates in the upstream `retry` library or `typeshed` itself.
