Ship NVIDIA's DLSS library in the setup and the build kit, and put it beside the game.

Browse Source 
The release carried AMD's FSR 3.1 library but not nvngx_dlss.dll, so DLSS ran only where the NVIDIA driver supplied the model itself; elsewhere players had to fetch the DLL by hand. tools/make_launcher.py and tools/make_kit.py now download NVIDIA's own build from the DLSS SDK repository at a pinned tag (tools/dlss_pin.py: 310.9.1, checked against its size and SHA-256, cached), and put it in the release's bin/ with a notice naming the NVIDIA RTX SDKs License that covers it. --dlss FILE takes a copy on disk instead, --no-dlss leaves it out.

tools/make_game.py copies the DLL and its notice beside the game. A different nvngx_dlss.dll the player put there is kept; the one an earlier build placed (named by the notice's sha256 line) is replaced, so a newer release can bring a newer DLSS. The compile step's key covers make_game.py and the kit version, so existing installs get the DLL with their next update.
