feat: implement Phase 10 - minimal skeleton with empty grid

Create clean src/ structure with minimal viable implementation:

Core Files:
- src/types.ts: Basic type definitions (Difficulty, GameStatus, GameManager)
- src/index.ts: Main package exports
- src/game.css: Copied from src_old for styling
- src/useGame.ts: Orchestrator with mocked GameManager API
- src/useBoard/useBoard.ts: Renders empty 9x9 sudoku grid

Implementation Details:
- useBoard renders 81 cells with sudoku-grid/sudoku-cell classes
- Each cell has data-r and data-c attributes for identification
- useGame provides full GameManager interface to satisfy example app
- Real implementations: gameStatus, keyLog tracking, game controls
- Mocked implementations: cursor ({}), scoreManager (zeros/null)
- Supports optional platformHook parameter

Build Status:
- TypeScript compiles cleanly with no errors
- Example app builds successfully
- Ready for browser testing with empty grid display

Phase 10 complete. Next: Phase 20 (full useBoard with puzzle generation).

## Iteration 2: [Pending]
## Iteration 2: Phase 10 - Minimal Skeleton
**Date**: 2025-01-22
### Goals
- Create clean src/ directory structure
- Implement minimal types
- Build empty 9x9 grid rendering
- Mock GameManager API for example app
- Get visual feedback without errors
### Tasks Completed
#### 1. Created Core Structure
```
src/
├── game.css [COPIED] - From src_old
├── index.ts [CREATED] - Main exports
├── types.ts [CREATED] - Basic type definitions
├── useGame.ts [CREATED] - Orchestrator with mocks
└── useBoard/
└── useBoard.ts [CREATED] - Empty grid rendering
```
#### 2. Implemented Types (src/types.ts)
- `Difficulty` - Puzzle difficulty levels
- `GameStatus` - Game state machine states
- `GameOptions` - useGame configuration
- `GameManager` - Full API interface (mocked for now)
- `KeyLogEntry` - Keystroke tracking
#### 3. Implemented useBoard (src/useBoard/useBoard.ts)
- `containerRef` - DOM reference
- `renderBoard()` - Renders empty 9x9 sudoku grid
- Creates proper HTML structure with `sudoku-grid` and `sudoku-cell` classes
- Sets data attributes (data-r, data-c) for cell identification
#### 4. Implemented useGame (src/useGame.ts)
- Calls `useBoard()` for grid rendering
- Returns full `GameManager` interface
- Real implementations:
- `gameStatus` state management
- `startGame`, `togglePause`, `quitGame`
- `keyLog` tracking with `clearKeyLog`, `getKeyLog`
- Mocked implementations:
- `cursor` (empty object)
- `scoreManager` (zeros and null)
- Supports optional `platformHook` parameter
#### 5. Verified Build
- ✅ TypeScript compilation successful
- ✅ Example app builds without errors
- ✅ No runtime errors expected
### Technical Details
**Empty Grid Rendering**:
- 81 cells (9x9) created with `sudoku-cell` class
- Each cell has `data-r` and `data-c` attributes
- Wrapped in `sudoku-grid` div inside `#sudoku` container
- Uses CSS from src_old for styling
**Mocking Strategy**:
- Return full GameManager interface to satisfy example app
- Mock methods do nothing (empty functions)
- Mock values return defaults (0, null, empty arrays)
- Real state management only for critical path (gameStatus)
### Next Steps
- Phase 20: Implement full useBoard with SudokuGenerator
- Port puzzle generation logic
- Add board state management
- Implement cell validation
