fix(desktop): allow reopening the macOS window from File menu - #28054

Exercise the registered closed handler.

548-583: Trivial · Maintainability & Code Quality · Quick win

Exercise the registered closed handler.

The direct Ref.set bypasses the production "closed" callback. The fixture replaces ElectronWindow.clearMain with a synchronous state reset, so invoking the handler can detect missing handler wiring or a missing call to clearMain, but it cannot detect a regression in production clearMain or validate its argument.

Suggested fix

-          yield* Ref.set(mainWindow, Option.none());
+          const closed = fakeWindow.windowListeners.get("closed");
+          if (!closed) {
+            return yield* Effect.die("window closed listener was not registered");
+          }
+          closed();
+          yield* Effect.promise(() => Promise.resolve());

In the test flow before `menu.configure`, replace the direct
`Ref.set(mainWindow, Option.none())` with invoking the registered `"closed"`
listener on the fake window, and wait for its effects to complete before
continuing. This exercises the production close-handler wiring and its call to
`clearMain`.

Use Effect.fn for the reusable menu operation.

Define activateMainWindow with Effect.fn("desktop.menu.activateMainWindow"). Remove the separate withSpan, and call activateMainWindow() from the click handler.

As per coding guidelines, “Reusable functions use Effect.fn("Service.operation")” and “Keep Effect.gen for inline programs and layer construction.”

Replace the callback-wiring test with a window-reopening regression.

The test replaces DesktopWindow.activate with a Deferred completion. It proves that the click reaches the stub, not that a closed window reopens.

Use the real DesktopWindow service with external Electron fakes. Trigger the close handler, await its completion, and invoke Open Window without a focused window. Assert that the main window is recreated. Extend an existing behavior test if one fits.

As per coding guidelines, omit tests for “callback wiring” and “Don't mock the logic under test.” The path instructions also require tests at the lowest layer that reproduces the regression.
