Replace wrestool with native Rust PE icon extraction (pelite)

- Add icons.rs to nak crate: parses PE resource sections, extracts
  RT_GROUP_ICON/RT_ICON and builds ICO files in memory
- Expose nak_extract_exe_icon() FFI for C++ consumption
- Update iconForExecutable() to use Rust FFI instead of shelling out
  to wrestool; reads all ICO entries for correct color depth
- Fix BasicGamePlugin::gameIcon() to call iconForExecutable() (was
  returning empty QIcon, causing placeholder icons for BG3/Cyberpunk)
- Move app icon setup: setDesktopFileName + setWindowIcon to
  MOApplication constructor (fixes Wayland taskbar/decoration icon)
- Move data/com.fluorine.* to data/icons/, install to XDG paths at
  launch for Wayland compositor icon resolution
- Remove icoutils dependency from Docker image and build output
