Fix Stage Manager window slide when closing popover

[noah30000]

Problem

When closing the Allkdic popover with the hotkey, windows from other
apps (e.g. Chrome) slide to the side stage in Stage Manager. This is
caused by NSApp.activate(ignoringOtherApps: true) in openPopover(),
which triggers Stage Manager to treat the app activation as a scene
switch. When the popover is then closed, Stage Manager animates the
transition back, making other windows appear to slide sideways.

Solution

Removed NSApp.activate(ignoringOtherApps:) from openPopover().
NSPopover shown relative to a status bar button works correctly without
activating the app, and Stage Manager no longer slides other windows.

Testing

Tested with Stage Manager enabled on macOS 26.5. Chrome no longer
slides when opening/closing the Allkdic popover.

Summary by cubic

Prevent Stage Manager from sliding other app windows when toggling the Allkdic status bar popover. Removed NSApp.activate(ignoringOtherApps: true) from openPopover() so showing the popover doesn’t trigger a scene switch.

Thanks for the clear write-up and Stage Manager-specific test notes. The root cause makes sense: avoiding foreground app activation for a status-item popover should prevent Stage Manager from treating it like a scene switch. If you want a full code review pass from me, request my review and I’ll run through the diff properly. (｡•̀ᴗ-)✧

@typeey can you review if this can lead a side effect or any regressions

[typeey]

No actionable side-effect or regression risk found in this change. The removed activation was only on the popover-open path; the code still explicitly activates when opening real Preferences/About windows, while status-item clicks, the Carbon global hotkey, transient popover dismissal, and the existing focus notification path remain intact.

Thanks so much for this, @noah30000! 🙏 The diagnosis was spot-on — pinpointing NSApp.activate(ignoringOtherApps:) as the Stage Manager trigger, plus the clear write-up and testing notes, made this a breeze to review and merge.

This is bundled into 2.2.3, which is currently in App Store review — it'll go live automatically once Apple approves. Really appreciate the contribution! 🎉
