According to https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p2300r10.html#spec-execution.senders.consumers.sync_wait, it has to return an engaged optional (on the value channel).

See https://github.com/NVIDIA/stdexec/blob/45c0f5803c190366a8529833901d1f6340b40d2e/include/stdexec/__detail/__run_loop.hpp#L50.

The run-loop must be started on the thread on which the operation state is started, so that the stdexec::get_start_scheduler query holds by construction.
