feat(dominion): add recommended kingdom presets and update deck mode UI
- Introduce four new recommended kingdom decks from the 2nd-edition rulebook: Size Distortion, Deck Top, Silver & Gold, and Helpful Actions.
- Refactor `kingdomFor` to use a `KINGDOM_PRESETS` mapping for cleaner extensibility.
- Update the Opponent Select Scene UI to display all deck mode options in a 3-column grid layout.
```
- Implement pure state engine (`DominionLogic.js`) with turn lifecycle, card effects queue, and pending decision resolution for complex interactions.
- Add card definitions and kingdom pool (`DominionCards.js`) supporting Standard and Random deck modes.
- Create AI logic (`DominionAI.js`) using Big Money/early engine strategies scaled by opponent skill.
- Build Phaser scene (`DominionGame.js`) with supply/hand rendering, turn drivers, modal prompts for pending decisions, and end-game scoring.
- Wire up game registry, routing, preload assets, and opponent selection UI to support the new mode.
