Scaffold RogueHunter: roguelike deck-builder on Phaser 4 + React

Vite + TypeScript + React 19 shell hosting a Phaser 4 game canvas,
structured as a Slay the Spire-style single-player deck-builder.

Architecture - strict core/render split:
- core/ holds all game rules as pure TypeScript with zero Phaser
  imports, so the domain is deterministic and engine-agnostic:
  - cards/      data-driven card model, library, and starter deck
  - combat/     turn-based CombatEngine (energy, block, draw/discard/
                exhaust piles, enemy intents) + enemy definitions
  - run/        RunManager (deck/hp/gold) and seeded MapGenerator
  - shared/rng  seedable mulberry32 for reproducible runs
- game/ is the Phaser layer: it renders core state and forwards input
  - scenes/     Menu -> Map -> Combat -> Reward -> GameOver
  - components/ CardSprite, CombatantSprite, Button
  - events/     typed EventBus bridging combat/run state to a React HUD
  - config/     centralized scene keys, colors, fonts, layout constants

Playable loop: traverse a deterministic 10-node map, fight turn-based
card combat against enemies with telegraphed intents, pick a card
reward after each win, culminating in a boss.

Verified: npm run lint and npm run build pass.

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+
+## React Compiler
+
+The React Compiler is enabled on this template. See [this documentation](https://react.dev/learn/react-compiler) for more information.
+
+Note: This will impact Vite dev & build performances.
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
