This commit implements the automatic lightweight mode feature with timer functionality:
- Rename configuration properties from auto_enter_lite_mode to enable_auto_light_weight_mode and auto_enter_lite_mode_delay to auto_light_weight_minutes for better clarity
- Add window event listeners to detect when window is closed or gets focus
- Implement timer system to automatically enter lightweight mode after configured time
- Remove exit_lightweight_mode function as it's no longer needed with the new implementation
- Update UI components to reflect the new property names
- Add logging for lightweight mode operations
- Initialize lightweight mode based on user configuration at startup
The feature now allows users to set a timer that will automatically enter lightweight mode
after closing the main window, which can be cancelled by focusing the window again.
Replace multiple boolean variables with a bitflag approach for tracking
required update operations in the patch_verge function. This improves
code maintainability and potentially performance by:
1. Using a single integer variable with bit operations instead of multiple booleans
2. Defining clear flags as enum variants for better code readability
3. Simplifying flag checks with bitwise operations
The UpdateFlags enum provides a clear and type-safe way to represent
different types of updates needed when patching Verge configuration.
