Contributions summary:Jeremy implemented a `HunterBot` within the Scala codebase. This involved creating the `HunterBot` class, defining its behavior, and integrating it with the game's logic. The user also made related changes to the `Parser`, `Game`, `Board`, and `Positionable` classes to support the new bot and correct parsing functionality. The work appears focused on implementing and refining the game's AI bots.
