fix(macos): keep overlay interactive when mpv loses foreground

- Track overlay mouse interaction state via IPC setIgnoreMouseEvents hook
- Skip macOS hide/passthrough when overlayInteractionActive is set
- Focus overlay window so lookup keys reach it during interaction
- Record mpv duration events into AniList media state for threshold checks
