Subject: [PATCH] feat: Add tic-tac-toe game with compact messaging
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

🎮 New Tic-Tac-Toe Game Features:
- Compact 3x3 board display using ASCII art
- Smart AI opponent with win/block/random strategy
- All messages under 200-character meshtastic limit (tested: 10-50 chars)
- Player vs Bot gameplay with X (player) vs O (bot)
- Win detection for rows, columns, and diagonals
- Tie game detection when board is full
- Game statistics tracking (games played, won)

🔧 Integration Features:
- Follows established game patterns from hangman/hamtest
- Added to restrictedCommands (DM-only like other games)
- Integrated with game tracker system for memory cleanup
- Added configuration option in config.template
- Automatic cleanup of stale game sessions

🎯 Game Mechanics:
- Players pick positions 1-9 corresponding to board layout
- Simple input parsing (extracts first digit from message)
- Graceful error handling for invalid moves
- 'end' command to quit game
- Automatic game cleanup on completion

📊 Message Examples:
- New game: 39 chars
- Game moves: 50 chars
- Win/lose: 40 chars
- Invalid move: 23 chars
- All well under 200-char limit

Tested: Complete game scenarios, AI behavior, message lengths
Follows: Existing game implementation patterns and memory management
