VO: Better Dogs

[5.0.39+26.3]

Added & Refactored

• Morning Gift Bringing & Feeding Merits System (WolfGiftGoal, WolfGiftHelper, WolfPersistentData):
• Implemented morning approach AI where healthy, monster-free dogs approach waking owners at $1.25\times$ speed to present scavenged gifts.
• Enforced 10-meal feeding merit threshold (bd_gift_feed_threshold), consuming 10 merits upon delivery with strict 1-day cooldown tracking.
• Implemented personality-themed scavenged gift loot pools (Aggressive: combat drops/bones/eyes; Pacifist: berries/apples/flowers; Normal: utility/sticks/feathers) plus 5% rare treasures (gold nuggets, emeralds, name tags, bone meal).
• Emits happy villager celebration particles via WolfParticleHelper and ambient audio cues upon gift delivery.
• Added automated test suite MorningGiftTest asserting threshold gating, merit deduction, daily cooldown math, health eligibility, and null safety.
