The bridge follow-up from sidorares/react-x11#951. useIdle on macOS now uses native.lastInputMs() when the bridge has it, and shells out to ioreg … HIDIdleTime (a child per poll) otherwise. With this shipped, react-x11 needs no JS change.

native.lastInputMs(): number: milliseconds since the last keyboard, mouse, trackpad or tablet event in the login session, from any app. It is CGEventSourceSecondsSinceLastEventType(kCGEventSourceStateCombinedSessionState, kCGAnyInputEventType) * 1000.

• It needs no permission and makes no AppKit call. It answers synchronously on the calling thread: before initApp, in pump mode, and from a worker with the main thread in runMain. It's listed in the README's "unchanged, on the calling thread" row.
• It is not ioreg's HIDIdleTime. The two are kept separately: they agree at a desk, but on CI's VMs lastInputMs ran 3–5 s longer.

Test: test/last-input.js is in npm test and CI. A test can't make or withhold the user's input, so it checks only what holds either way:

• Before initApp, it returns a finite number ≥ 0.
• Across two reads 300 ms apart, it either grew by the time between them or was reset by input.
• It logs HIDIdleTime beside lastInputMs for comparison, without asserting anything about the two.
• From a worker, with the main thread parked in runMain, it returns a number synchronously.
