manaflow-ai#12359's HoverWindow declares a stored `keyWindow`, but NSWindow already has a `keyWindow` property (imported with the getter `isKeyWindow`), so the test target fails with "cannot override with a stored property 'keyWindow'". The same test passes a point to `convertToScreen(_:)`, which converts rects. Rename the stored flag and convert the pointer with `convertPoint(toScreen:)`. The test still checks the same hover transitions.

Summary
Cloud sidebar hover controls now have one owner:
CloudTreeNSOutlineViewtracks the current visible cell and drives its action-host visibility. This prevents stale X/actions from remaining visible after pointer exit, row-to-row transfer, scrolling, reload/refresh/reconnect, or cell reuse. Window deactivation clears hover, and window activation recomputes it for a stationary pointer.Fixes #12355.
Testing
