Update animation demo suite with crash fixes and improvements
- 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. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
