Description

Explore some way to combine/bring in CAF (cancelable async functions) capabilities so that fasy's async iterations are optionally cancelable.

This might need to be a separate namespace where the API methods assume the cancelable token being passed in, or it may just be that existing methods could be polymorphic in some way.

Also to be explored: should fasy re-implement the cancelation, or should there be an adapter that can be optionally applied which delegates to CAF (which would need to be present separately) when needed.

Contributor guide

Research direction
Investigate CAF (cancelable async functions) and design an integration strategy for fasy, considering either a separate namespace with token passing or an adapter pattern that delegates to CAF. Evaluate trade offs between reimplementing cancellation and relying on an external library.
