fix(jellyfin): fix overlay toggle sync, redirect reload, and AppImage bi

- Sync visible-overlay state back to plugin via script messages to avoid toggle/hide drift
- Collapse duplicate toggle events within 250ms to prevent hide-then-show on single keypress
- Preserve manual hide across Jellyfin path-changing redirects even when media-title drops
- Rearm managed subtitle defaults on path-changing redirects
- Route toggleVisibleOverlay session binding through plugin toggle instead of app-side IPC
- Show Linux/Hyprland overlay passively (showInactive) to avoid stealing mpv keyboard focus
- Fix AppImage binary resolution to prefer $APPIMAGE env over mounted inner binary
- Add stats window layer management so delete/update dialogs appear above stats window
- Fix Jellyfin remote progress sync during Linux websocket reconnect windows
