Coffee GB 2.0.5

Coffee GB 2.0.5 improves compatibility with unlicensed cartridges and four-player/link games, adds substantial Android PERFORMANCE-mode throughput, and completes the desktop library/settings refresh. It also carries the Super Fighters S protection/vector compatibility work and preserves the new serial/link phases in portable state. Contributors in this release include @trekawek.

The release range also includes direct commits for Jantaku portable serial state (c8c8b3b1), Jantaku transition handling (904bae12), Super Fighters S support (848b83c6), and linked-playback capture/state fixes (6c066296).

Native packages in this release are unsigned. On macOS, game controllers require a compatible system SDL2 installation; keyboard input and emulation remain usable without it.
