- Add create_debounced_window_state_saver() function in window.rs
- Extract WINDOW_STATE_FLAGS_TO_SAVE and WINDOW_STATE_SAVE_TIMEOUT constants
- Listen to tauri://move and tauri://resize events with 5-second debouncing
- Automatically save window state after positioning changes settle
- Prevent window position loss during system shutdowns/restarts
The debouncing mechanism avoids excessive disk I/O during active window
manipulation while ensuring recent position changes are preserved even
when the application doesn't close normally.
Fixes window position being lost when system restarts before user
manually closes the application.
