[TURBO] Auto power plan switching

[HuckleR2003]

Milestone: v1.7.7
Goal: Automatically switch to "High Performance" power plan when gaming, revert when done.

Why this works:

• Balanced plan: CPU throttles to save power
• High Performance: CPU runs full speed always
• Simple but effective (+10-20% performance)

Detection triggers:

• Fullscreen game launched
• TURBO mode manually enabled
• Specific .exe running (user-defined list)

Power plans:

• Balanced (GUID: 381b4222-f694-41f0-9685-ff5bb260df2e)
• High Performance (GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c)
• Power Saver (for laptop battery mode)

Implementation:

• powercfg /list (enumerate available plans)
• powercfg /getactivescheme (get current)
• powercfg /setactive [GUID] (switch)

Logic:

1. Detect game launch → switch to High Performance
2. Game exits → switch back to Balanced
3. Laptop on battery → override to Power Saver (optional)

UI:

• Current power plan indicator
• Auto-switch toggle (ON/OFF)
• Manual plan selector (for testing)

Safety:

• Always restore original plan on PC_Workman exit
• Battery mode override (don't use High Performance on battery)
• User can disable auto-switch

Success:

• Performance gains in CPU-bound games
• Zero manual intervention needed
• Battery life preserved when unplugged
• Works seamlessly
