Detailed Description

Non-owning erased identity for one Uni20 coroutine frame.

The coroutine pointer, promise pointer, and concrete-promise domain are always captured together from the original typed coroutine handle. A TaskHandle does not add or release an ownership claim and never destroys a frame automatically.
