- macOS tracker now reports minimized vs not-found so transient helper misses no longer hide the overlay; minimizing mpv still triggers hide
- overlay-runtime-init skips hide on non-minimized window-lost and calls updateVisibleOverlayVisibility instead
- overlay-visibility preserves window level and passthrough state during transient tracker loss
- subsync modal open uses dedicated modal window with retry logic to fix first-attempt flash and stale modal state on macOS
