Per-app automatic refresh rate switching

[SilasSch]

Feature

Automatically switch refresh rate when specific apps are launched/closed.

Suggestion

• Config section in config.json:

{
  "profiles": [
    { "processName": "fc26.exe", "refreshRate": 120 },
    { "processName": "chrome.exe", "refreshRate": 60 }
  ]
}

• Background thread monitors running processes
• Switches rate when profile app starts/stops

Why

Ultimate convenience — gaming app opens? 120Hz. Closed? Back to 60Hz. No manual interaction needed.
