Bell of Companions

Note: Some fixes may not be fully verified in all situations.

Added:

• Vanilla cooldown overlay for the Pet Bell and Pet Tagger (white sweep animation in hotbar).

Fixed:

• Pet List no longer shows an empty portrait box for unloaded pets with no preview - slot now shows a dark background.
• Live owned pets now always provide preview snapshot data to the Pet List, preventing some pets from appearing without a portrait.
• Distant unloaded pets no longer show the death pose in the Pet List preview when they are alive.
• Tagged pets across all loaded worlds are now discovered when pet_list_nearby_only is off, and written back to the registry.
• Revived pets no longer immediately re-die from stale state; health, death timer, hurt timer, fall distance, and velocity are cleared on revival.
• Pet registry file relocated to data/bell-of-companions/ (namespaced subfolder); existing files are auto-migrated.
• Pet NBT snapshots now strip transient fields (FallDistance, Motion, HurtByTimestamp, etc.) before saving.
