docs(cancellation): correct Corosio backend cancellation claims#330
Conversation
The OS Integration section listed only IOCP and io_uring and presented io_uring as the Linux mechanism. Corosio's default backend selection is IOCP > epoll > kqueue > select; io_uring is opt-in, so Linux defaults to epoll, not io_uring. Describe cancellation by backend class instead: completion-based backends (IOCP, io_uring when enabled) cancel in the kernel, while readiness-based backends (epoll, kqueue, select) remove the pending operation from the reactor before its syscall runs. State the reported error, std::errc::operation_canceled, and drop the fragile per-syscall names.
