Brillo 2.0 - Production ready 2D graphics

Congrats! Looks like a lot of updates to Gloss (CHANGELOG.md > 2024, 2026). I confirm that Tetris ran on an arm mac, macos tahoe 26.2. (How-to: download, try to run it once, go to mac’s Settings > Privacy & Security, scroll to the bottom, allow brillo-tetris, run again, confirm dialogs.)
