refactor OpFinishHandle's handling of cqe

[wokron]

The original set_result() function only accepted res and flags, which lacked extensibility. Therefore, it has been refactored into a handle_cqe() function.

Pull request overview

This PR refactors completion handling for io_uring operations by replacing OpFinishHandle::set_result(res, flags) with a more extensible handle_cqe(io_uring_cqe*) flow, and updates runtime/test code to use the new CQE-driven handling (including multishot and zero-copy behaviors).

Changes:

• Replaced set_result() usage with handle_cqe() across runtime and tests.
• Reworked multishot/zero-copy completion behavior to be handled under WorkType::Common via an Action return contract.
• Updated tests and WorkType to reflect the new completion-dispatch approach.
