Keep clipboard panel above full-screen apps

[bifrost-proxy]

Summary

• raise the clipboard panel to the assistive-technology overlay level
• attach every hotkey presentation to the active full-screen Space and verify WindowServer visibility
• recover from stale visibility, Space transitions, occlusion, and interrupted dismissal races
• add a deterministic full-screen overlay regression to CI and Release

Verification

• swift build
• localization/history/settings/updater/appearance/translation verifiers
• panel overlay recovery and panel reconciliation regressions
• isolated and installed three-launch UI regressions
• real iCloud three-launch regression via LaunchServices with cleanup
• Universal 1.7.7 (50) DMG/signature/architecture verification
• memory performance regression
• strip functional/performance assertions (local RSS gate also fails on unmodified 1.7.6 baseline)

Avoid reclaiming focus when another app activates

When the user switches applications with Cmd-Tab while the panel is open, this handler calls beginVisibilityRecovery(), which synchronously reaches restorePresentationPolicyAndOrdering() and panel.makeKey(). That can run before the deferred windowDidResignKey check, causing that check to see the panel as key again and abort its auto-hide, so Pesty steals focus back from the newly activated application. Application activation should only initiate reattachment after confirming the panel is detached, without immediately making it key.

Resolve callbacks when presentation interrupts dismissal

If show() runs during the 80 ms hide animation, it increments presentationGeneration, so this guard discards the hide completion without removing or invoking hideCompletions. For pasteItem, that suppresses the requested paste, and the retained callback then executes during a later unrelated hide, potentially pasting the stale item into the previously captured application. An interrupted dismissal must explicitly cancel or complete its queued callbacks rather than leaving them for the next hide.
