SkyNET SDL 1.3.0

Faster Android, and a fix for the Android setup screen hang.

Changes

• Android is much faster. The game's code is now compiled the same way as on the desktop (NativeAOT instead of Mono). On a phone with a Snapdragon 8 Gen 3 the trench demo runs at about 64 fps instead of 45 (+40%), and maps load about 6 s faster. The CPU-heavy parts (robots, physics, building each frame) gain the most, so slower phones should feel it too.
• #11 fixed: on some starts the Android setup screen stayed black and nothing happened after picking the game folder. Its first dialog was drawn 0 pixels wide, so it was invisible. It now always shows.

Downloads

File	What it is
skynet-sdl-1.3.0-win-x64.zip	Windows x64: skynet-sdl.exe (game) and SkyNetEdit.exe (editor). Unzip anywhere, or into the SkyNET folder, then run skynet-sdl.exe --data <the game's data folder>.
skynet-sdl-1.3.0-linux-x64.tar.gz	Linux x64 (glibc 2.35+, a Vulkan driver): ./skynet-sdl --data <the game's data folder>; the editor is ./SkyNetEdit.
skynet-sdl-1.3.0-osx-arm64.tar.gz / -osx-x64.tar.gz	macOS on Apple Silicon / Intel (Metal). The binaries are not signed: after unpacking run xattr -dr com.apple.quarantine skynet-sdl-1.3.0-osx-* once.
SkyNET-1.3.0.apk	Android (arm64, Vulkan). Installs over 1.2.x; your folder, settings and saves stay.

The optional HD mod skynet-hd.zip is unchanged: download it from the 1.2.1 release. On tablets and phones with little graphics memory, play without it or with the original look.

The Linux and macOS archives are added by the build a few minutes after the release.
