feat(test): honor io_env::stop_token in capy::test awaitables (#317)#336
Conversation
…iance#317) All capy::test mock awaitables now resolve to error::canceled when the environment's stop token is requested, so code under test can exercise its cancellation paths against the mocks. The synchronous mocks check the token up front; stream::read_some wakes a blocked read via a stop callback while preserving its synchronous fast path when data is already buffered. io_env reaches an awaitable only through await_suspend, so the synchronous mocks must suspend once to observe it. They return false from await_suspend (conditional no-suspend) rather than self-transferring via the returned handle: the return-h form leaks the awaiting coroutine frame under run_async. Also removes now-unused <stop_token> includes from the any_* tests.
