Update v0.1.4

I think it's time to release a new version.

Changelog:

• Refactored character state management for better scalability and maintainability.

• Switched character movement from interpolation to physics-based motion.

• Added a prey-chasing behavior.

• The probability of initiating a chase depends on the number of characters in sight, hunger level, and aggression.

• Characters will give up the chase if the prey is eaten by another predator, changes floors, or leaves the field of view.

• Tweaked the predator-prey interaction mechanics.

• Stomach acid level now increases based on belly size.

• Revival no longer requires waiting for the next day — watch a 60-second ad to revive instantly ^o^ (just kidding).

• Gave the scene interior a bit of a makeover.

• Added a free camera mode — drag with right mouse button and zoom with the scroll wheel.

• Added a button to fast-forward time and skip the night.

• Some other minor tweaks and polish.

• Fixed several bugs.

If you find any bugs or have any suggestions, please tell me.
