Adds the ability to automatically change the power mode in Linux Mint on laptops depending on the power source state (AC or battery).

The tool monitors power connection events and:

automatically switches to a power-saving (or user-selected) mode when the laptop is disconnected from AC power and running on battery;
automatically switches to a performance (or user-selected) mode when the laptop is connected to AC power;
shows a desktop notification when the power mode is changed (except during system startup);
does not switch the power mode if the current profile already matches the required one (for example, after a manual change).

This helps optimize battery life, performance, and power consumption without manual interaction.
