Detailed Description

template<typename T>
class aria::async::WhenAnyCancellableAwaiter< T >

Awaitable that resolves when ANY of the input task FACTORIES completes (success or error).

Each factory receives its own CancellationToken; when a winner is established, every loser's token is fired so cooperative inner work unwinds promptly instead of running to completion in the background.

Note: cancellation is best-effort. Inner work that ignores its token still runs to completion off-stage; only its result and exception are dropped.
