Rebecca Totem

Performance update

• Replaced automatically generated item geometry with a lightweight, two-face model.
• Removed geometry along the artwork outline to reduce rendering work while the totem is visible.
• Kept the 256 x 256 artwork, animated blinking, gradual smile, eye glint, and compact first-person positioning.
• Retained the public pack's synthetic cyberpunk activation sound.

Checked in game on Minecraft Java 1.21.8. This update addresses reported frame-rate drops; the improvement depends on your setup, and no specific FPS increase is guaranteed.
