Patch Review

The `Registration::new` method now accepts `impl PinInit<F::Of<'a>, E>` and transmutes to `'static` for storage:
```rust
let data: Pin<KBox<RegistrationData<F::Of<'static>>>> =
    unsafe { core::mem::transmute(data) };
```
This is the first explicit `transmute` for lifetime erasure. The reasoning is sound (lifetimes are erased at runtime) but this pattern should be documented as a general policy.

The `registration_data` retrieval correctly shortens back from `'static` to `&self`'s lifetime via `ForLt::cast_ref`.
