v0.4.0

Changed

• Native Qt app. The window is now built with Qt Widgets from Rust instead of an embedded web
  page (HTML/CSS). Same layout: header over the mod list, details and launch controls on the
  right. The look follows the Windows light/dark setting, with the Windows 11 style where it is
  available and a neutral Fusion style on Windows 10.
• Groups are real tree rows: fold them with the arrow, tick the header to turn the whole group
  on or off, and drag a group to move all of its mods.
• The app now ships as a zip (TKModManager-x64.zip: the exe plus its Qt files) and updates in
  place from it.

Removed

• The per-mod manual script-extender override. A mod needs the script extender only when its
  pack has SE/script_extender.json.

Upgrading from 0.3.x

• 0.3.x looks for a single exe in the release and will say there is no update. Download
  TKModManager-x64.zip once, unpack it into a folder and start TKModManager.exe. Settings,
  profiles, notes and downloaded DLLs are kept (they live in %APPDATA%\TKModManager).
