⚡ [Powerplan] Replace inefficient polling loop with event-driven WinWait

[Ven0m0]

💡 What: Replaced the infinite Sleep and WinExist polling loop with WinWait and WinWaitClose inside ahk/Powerplan.ahk. Removed the fortniteWasRunning state variable as the execution inherently waits.

🎯 Why: The previous script was polling the system every 5 seconds (5000ms via DllCall), creating unnecessary CPU wake-ups and creating up to 5 seconds of latency when the game opens or closes before the power plan would actually switch. WinWait completely halts execution of the thread at the Windows API level until the target window appears or disappears, reducing CPU impact to nearly zero and switching power plans instantly upon launch or exit.

📊 Measured Improvement:

• Cannot dynamically benchmark locally because AutoHotkey cannot be executed in the current Linux environment.
• Theoretically, the complexity changes from O(1) polling every 5 seconds (constant CPU wakeups and context switches) to an event-driven hook via the OS. Latency drops from an average of ~2.5s (max 5s) to <10ms. Lines of code are reduced and state tracking logic is eliminated.

Pull request overview

Updates the ahk/Powerplan.ahk AutoHotkey v2 utility to switch Windows power plans based on Fortnite window lifecycle using blocking waits instead of a periodic polling loop, aiming to reduce latency and unnecessary wakeups.

Changes:

• Replaced WinExist + Sleep(5000) polling with WinWait / WinWaitClose.
• Removed the fortniteWasRunning state-tracking variable and state-change branching.

[Copilot]

Run() is asynchronous, so if Fortnite opens/closes quickly you can end up with overlapping powercfg invocations and a race where the earlier launch command finishes after the close command (leaving the wrong power plan active). Consider using RunWait() (or capturing the PID and waiting for it to exit) for both powercfg calls to guarantee ordering.
