Improved Happy Ghast

✨ Major Improvements: Added Happy Ghast silencing via honey bottle (#3), fixed an internal loop bug in find/upsert handling, and updated documentation and showcase. This release supports Minecraft Versions 1.21.6–1.21.11.

Details:

• Silencing Happy Ghast: You can now right-click a Happy Ghast with a honey bottle to toggle its silence state on/off. Suggested in #3.
• Internal DB Fix (find/upsert loops): Fixed a bug in the internal players storage DB where loop execution could stop early after a match and leave the sentinel entry behind, which then caused follow-up lookup/insert issues. The loop flow now completes cleanly so sentinel cleanup remains consistent.
• Documentation & Presentation Updates: Updated the pack/advancement descriptions and README usage docs to include silencing, and refreshed showcase/about assets.
