Added job component and queue system

- Introduced a new JobComponent and JobQueue to manage jobs in the game.
- Created two new jobs: DigJob and InfectJob with their respective scripts.
- Updated CrystalGlowComponent, FreeCameraComponent, MushroomGlowComponent, WaterEffectComponent to improve logging messages.
- Adjusted camera movement limits in FreeCameraGameCameraComponent for better control.
- Added FiniteStateMachine class for managing states of entities.
- Implemented GlowingIdle state as an example of using the state machine.
- Included a utility function to fetch file paths by extension from a directory.
