Update animation demo suite with crash fixes and improvements

Browse source 
- Add warnings about AnimationManager segfault bug in sizzle_reel_final.py
- Create sizzle_reel_final_fixed.py that works around the crash by hiding objects instead of removing them
- Increase font sizes for better visibility in demos
- Extend demo durations for better showcase of animations
- Remove debug prints from animation_sizzle_reel_working.py
- Minor cleanup and improvements to all animation demos

These demos showcase the full animation system capabilities while documenting and working around known issues with object removal during active animations.

@ -5,12 +5,19 @@ McRogueFace Animation Sizzle Reel - Final Version
Complete demonstration of all animation capabilities.
This version works properly with the game loop and avoids API issues.
WARNING: This demo causes a segmentation fault due to a bug in the
AnimationManager. When UI elements with active animations are removed
from the scene, the AnimationManager crashes when trying to update them.
Use sizzle_reel_final_fixed.py instead, which works around this issue
by hiding objects off-screen instead of removing them.
