Mystify Demo, TwoEleven updates & Snake (#21)

* **New Features**
  * Added Mystify screensaver demo with animated polygons and trails
  * Added Snake game with multiple difficulties, high-score persistence, and multi-input (touch/keyboard) support
  * Added CLI tool for building, packaging, and deploying apps (end-to-end build/install/run workflow)
  * Per-grid-size high-score persistence added to 2048 app; expanded keyboard controls (WASD and device-specific mappings)

* **Documentation**
  * Added Snake README with gameplay, controls, and usage instructions
