//! Windows IOCP backend: overlapped I/O (`ReadFile` / `WriteFile` with
//! `OVERLAPPED`, completions reaped via `GetQueuedCompletionStatus`). Segment
//! files open with `FILE_SHARE_DELETE` so tombstone-rename protocols succeed
//! against held handles.
// Raw completion-port plumbing — an internal detail of this backend, never
// something an embedder drives directly.
