Restructure config.json with nested hierarchy and dot notation access

- Reorganized config.json into logical sections: connection, duck_spawning, duck_types, player_defaults, gameplay, features, limits
- Enhanced get_config() method to support dot notation (e.g., 'duck_types.normal.xp')
- Added comprehensive configurable parameters for all game mechanics
- Updated player creation to use configurable starting values
- Added individual timeout settings per duck type
- Made XP rewards, accuracy mechanics, and game limits fully configurable
- Fixed syntax errors in duck_spawn_loop function
