Unit tests

Type erased senders and Kokkos::Execution::ExecutionSpaceContext

This group of tests check that type erased senders are usable with Kokkos::Execution::ExecutionSpaceContext.

The key design point is that the type erased sender no longer knows the concrete sender type, so the only way to support environment‑based customization is via a fixed set of queries that the erasure wrapper promises to forward. See:
