1032-1035: Trivial · Maintainability & Code Quality · Quick win

Test the Python-facing WSARecvFromInto signature.

The only test, recvfrom_into_rejects_oversized_request_before_starting_io, calls the inner Overlapped::WSARecvFromInto with OptionalArg::Missing. It does not go through the new recvfrom_into method or its RecvFromIntoFlags parser. A regression in the flags default, positional-only binding, or forwarded value would not fail this test. Add a test that calls WSARecvFromInto through the Python attribute with omitted, positional, keyword, and invalid flags values.

Review comment at @crates/stdlib/src/overlapped.rs around lines 1032 - 1035:
The existing test bypasses the Python-facing `WSARecvFromInto` wrapper and does
not verify its argument parsing. Add a test that invokes `WSARecvFromInto`
through the Python attribute, covering omitted, positional, keyword, and invalid
`flags` values; verify the wrapper’s default, binding behavior, and forwarded
value without replacing the existing inner-method test.

- Line 57: Update CreateIoCompletionPort’s handle argument conversion so the
exported INVALID_HANDLE_VALUE is accepted without OverflowError: preserve
conversion of negative values to isize and convert nonnegative values through
the usize range before casting to isize. Follow the established conversion
pattern used by the Overlapped constructor.

Review comments at @crates/stdlib/src/overlapped.rs:
- Line 1138: Update the event conversion in the Overlapped constructor to
preserve positive Python integers above isize::MAX without wrapping them into a
negative value, while keeping the event getter’s returned value consistent with
the supplied event. Establish a representation and conversion path that supports
the accepted range and preserves existing validation behavior.

crates/stdlib/src/overlapped.rs-1244-1244: 1

1244-1244: Minor · Potential issue · Poor tradeoff

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

CreateIoCompletionPort now returns the host handle as usize, while the supplied GetQueuedCompletionStatus and PostQueuedCompletionStatus entry points still accept isize ports. A returned handle with its top pointer bit set may therefore be unusable by those consumers.

Argument conversion raises OverflowError before the completion-port operation reaches Windows.

This can occur when: Windows returns a valid completion-port handle whose pointer-width bit pattern exceeds isize::MAX, and a caller passes the returned Python integer to a completion-port operation.
