refactor(pio): update initialization logic and type definitions

- Changed the type of `pendingInit` to `number | undefined` for better type safety.
- Simplified the requestIdleCallback handling by using a local variable for window type.
- Improved readability and maintainability of the initialization scheduling logic.
