Refactor Pacman state handling to use setState method.

Centralized Pacman state transitions into a new `setState` method to improve clarity and consistency. Removed redundant `reset` and `startDeathAnimation` methods, merging their logic into state management. Adjusted game state transitions to align with the new approach.
