Adds a new T.Cleanup method to register cleanup functions. These will run after each iteration of a Check. The implementation of how cleanup functions are tracked and run is borrowed heavily from testing.T's own implementation. Namely: - [T.Cleanup puts functions in a slice](https://cs.opensource.google/go/go/+/refs/tags/go1.24.0:src/testing/testing.go;l=1214-1216) - [cleanups are run in reverse order](https://cs.opensource.google/go/go/+/refs/tags/go1.24.0:src/testing/testing.go;l=1433-1446) popping functions from the slice one by one - [panics are not allowed to interrupt cleanup](https://cs.opensource.google/go/go/+/refs/tags/go1.24.0:src/testing/testing.go;l=1420-1427) As with `testing.T`, cleanup runs after the context is canceled. Because Rapid's context is lazily initialized, it needs an additional check to avoid providing a valid context during cleanup. Resolves flyingmutant#62

Is this black magic taken from testing?

Yeah, from here: https://cs.opensource.google/go/go/+/refs/tags/go1.24.0:src/testing/testing.go;l=1420-1427
(Minus the two recovery modes. We don't need divergent behavior in this case.)
This is will basically still let the panic propagate outwards as a regular panic (we don't recover), but it'll make sure all cleanup functions are at least invoked.

Took another pass over the documentation for both functions. |

it needs an additional check to avoid providing a valid context
