  SmartFrameRedirect - a Cyber Engine Tweaks mod for Cyberpunk 2077
  ---------------------------------------------------------------
  Lets you type a custom folder path in an in-game window. Since CET's
  mod sandbox cannot spawn external processes (io.popen / os.execute
  are both unavailable to mods), this talks to a small separate
  PowerShell watcher (watcher.ps1, started via StartWatcher.bat) which
  must be running in the background. This mod just writes a small
  request.json file; the watcher does the actual folder-junction work
  and writes a response.txt back, which this HUD reads and displays.

  Requirements: CET, and watcher.ps1 running (via StartWatcher.bat).
