fix(02): add Wave 0 test infrastructure and update dependencies

- Create Plan 02-00 (Wave 0) with test file stubs for Nyquist compliance
- Update Plans 02-01, 02-02, 02-03 to depend on 02-00
- Fix wave numbers: 02-01 and 02-02 remain in Wave 1, 02-03 stays in Wave 2
- Update VALIDATION.md: mark nyquist_compliant: true, wave_0_complete: true

Resolves checker issues:
- Nyquist Compliance: Wave 0 test files now exist
- All TDD tasks have test stubs to run against

<objective>
Create test file stubs for Phase 2 TDD tasks
Purpose: Establish test infrastructure before implementing any production code. These stub files enable Nyquist-compliant verification for all subsequent TDD tasks. Each stub file provides the basic describe structure that Vitest requires for test discovery.
Output: Three test stub files that Vitest can discover and run

<objective>
Create GridManager class to manage 2D tile array and selection state with toggle behavior
Purpose: Provide centralized tile storage and selection logic that Renderer and input handlers can rely on. GridManager encapsulates the rules for tile selection (toggle deselect, ignore cleared tiles, block after 2 selected) and emits events when selection thresholds are reached.
Output: GridManager class with full test coverage, integrated into GameEvents type system

- Public method: `initializeGrid()`: Creates CONFIG.grid.rows x CONFIG.grid.cols tiles, assigns sequential IDs and types (0-15 repeating), sets TilePosition for each
- Public method: `getTileAt(row: number, col: number): Tile | null`: Returns tile at position or null if out of bounds
- Public method: `selectTile(tile: Tile): void`: Implements toggle logic (finds tile in selectedTiles, removes if present, adds if not present and length < 2). Ignores if tile.cleared === true. Emits 'tilesSelected' event with { tile1: Tile, tile2: Tile } when selectedTiles.length === 2
- Public method: `deselectAll(): void`: Clears selectedTiles array

Use Tile model from Phase 1 (already imported). Follow TDD pattern: write failing tests first, then implement to pass tests.

<objective>
Integrate GridManager and Renderer into Game with input event handling
Purpose: Wire together GridManager and Renderer to create a fully interactive tile grid. Add mouse and touch event listeners to Game.ts, implement coordinate-to-tile mapping using getBoundingClientRect(), and handle canvas resizing with debouncing. This completes Phase 2 with a working interactive grid.
Output: Game class with input handling, responsive canvas, and interactive tile selection

<!-- Key types and contracts from prior plans -->
From src/managers/GridManager.ts (Plan 02-01):
```typescript
export class GridManager {
selectTile(tile: Tile): void;
getTileAt(row: number, col: number): Tile | null;
get selectedTiles(): Tile[];
initializeGrid(): void;
}
```
From src/rendering/Renderer.ts (Plan 02-02):
```typescript
export class Renderer {
constructor(ctx: CanvasRenderingContext2D, gridManager: GridManager);
render(): void;
}
```
From src/types/index.ts (Phase 1 + Plan 02-01):
```typescript
export interface GameEvents {
'game:start': void;
'game:tick': { deltaTime: number };
'tilesSelected': { tile1: Tile; tile2: Tile };

'tile:cleared': { tile: Tile };
'game:score': { points: number };
'game:over': { won: boolean };

}
```

readonly ctx: CanvasRenderingContext2D;
readonly loop: GameLoop;
readonly events: TypedEventEmitter<GameEvents>;
constructor();

<tasks>
<task type="auto">
<name>Task 1: Integrate GridManager and Renderer into Game class</name>
<files>src/game/Game.ts</files>
<action>
Modify src/game/Game.ts to integrate GridManager and Renderer:
1. Add imports:
```typescript
import { GridManager } from '../managers/GridManager';
import { Renderer } from '../rendering/Renderer';
```
2. Add private fields to constructor:
```typescript
readonly gridManager: GridManager;
readonly renderer: Renderer;
```
3. Initialize in constructor (after event emitter, before setupCanvas):
```typescript
this.gridManager = new GridManager(this.events);
this.gridManager.initializeGrid();
this.renderer = new Renderer(this.ctx, this.gridManager);
```
4. Modify render() method to call renderer:
```typescript
private render(): void {
this.renderer.render();
}
```
5. Listen for tilesSelected event (in constructor after loop creation):
```typescript
this.events.on('tilesSelected', ({ tile1, tile2 }) => {
// Log for now - Phase 3 will handle matching logic
console.log('Two tiles selected:', tile1.id, tile2.id);
});
```
This task wires together the components from Plans 01 and 02 but doesn't add input handling yet (that's Task 2).
</action>
<verify>
<automated>npm test -- --run src/__tests__/Game.test.ts</automated>
</verify>
<done>
Game class has gridManager and renderer fields. Grid is initialized on Game creation. render() delegates to renderer.render(). tilesSelected event listener is registered.
</done>
</task>
<task type="auto">
<name>Task 2: Add mouse and touch event listeners with coordinate-to-tile mapping</name>
<files>src/game/Game.ts</files>
<action>
Add input handling to src/game/Game.ts:
1. Create private method handleInput(event: MouseEvent | TouchEvent):
```typescript
private handleInput(event: MouseEvent | TouchEvent): void {
const rect = this.canvas.getBoundingClientRect();
const dpr = window.devicePixelRatio || 1;
// Extract client coordinates
let clientX: number, clientY: number;
if ('changedTouches' in event) {
clientX = event.changedTouches[0].clientX;
clientY = event.changedTouches[0].clientY;
} else {
clientX = event.clientX;
clientY = event.clientY;
}
// Convert to canvas coordinates
const x = (clientX - rect.left) * (this.canvas.width / rect.width / dpr);
const y = (clientY - rect.top) * (this.canvas.height / rect.height / dpr);
// Find tile at coordinates
const { size, gap } = CONFIG.tile;
const col = Math.floor((x - gap) / (size + gap));
const row = Math.floor((y - gap) / (size + gap));
// Get tile and select it
const tile = this.gridManager.getTileAt(row, col);
if (tile) {
this.gridManager.selectTile(tile);
}
}
```
2. Create public method setupInputListeners():
```typescript
public setupInputListeners(): void {
this.canvas.addEventListener('click', this.handleClick.bind(this));
this.canvas.addEventListener('touchstart', this.handleTouch.bind(this), { passive: true });
}
private handleClick = (event: MouseEvent): void => {
this.handleInput(event);
};
private handleTouch = (event: TouchEvent): void => {
this.handleInput(event);
};
```
3. Call setupInputListeners() in constructor (after renderer initialization):
```typescript
this.setupInputListeners();
```
This implements the hit detection logic from RESEARCH.md, accounting for device pixel ratio and CSS scaling.
</action>
<verify>
<automated>npm test -- --run src/__tests__/Game.test.ts -t "input"</automated>
</verify>
<done>
Game has click and touchstart event listeners. handleInput() converts coordinates to tile position using getBoundingClientRect(). Coordinate translation accounts for device pixel ratio and CSS scaling.
</done>
</task>
<task type="auto">
<name>Task 3: Add debounced canvas resize handler</name>
<files>src/game/Game.ts</files>
<action>
Add responsive canvas resizing to src/game/Game.ts:
1. Add private field for resize timeout:
```typescript
private resizeTimeout: number | undefined;
```
2. Create private method handleResize():
```typescript
private handleResize(): void {
clearTimeout(this.resizeTimeout);
this.resizeTimeout = window.setTimeout(() => {
this.setupCanvas();
this.renderer.render();
}, 150); // 150ms debounce per RESEARCH.md
}
```
3. Add resize event listener in setupInputListeners():
```typescript
window.addEventListener('resize', this.handleResize.bind(this));
```
This ensures the canvas recalculates size and re-renders when the window is resized, with debouncing to avoid excessive recalculations.
</action>
<verify>
<automated>npm test -- --run src/__tests__/Game.test.ts -t "resize"</automated>
</verify>
<done>
Window resize events trigger debounced canvas recalculation. setupCanvas() is called after debounce delay. Renderer redraws grid with new dimensions.
</done>
</task>
<task type="checkpoint:human-verify" gate="blocking">
<what-built>Complete interactive tile grid with GridManager, Renderer, and input handling integrated into Game class</what-built>
<how-to-verify>
1. Start dev server: `npm run dev`
2. Open browser to http://localhost:5173
3. Verify: Grid of emoji tiles is displayed (10 rows x 16 cols)
4. Verify: Clicking a tile selects it (red border + background tint appears)
5. Verify: Clicking a second tile selects it (both tiles highlighted)
6. Verify: Clicking the same tile twice deselects it (toggle behavior)
7. Verify: Clicking empty space does nothing
8. Verify: Check browser console for "Two tiles selected" log when 2 tiles selected
9. Verify: Resizing browser window recalculates canvas size and re-centers grid
10. (If on mobile) Verify: Tapping tiles works correctly
