Human and Dog

**Added**
- Choose the dog's age (puppy / adult) right after picking the dog role, then pick a wolf variant.
  Puppies grow up after 20 minutes; feed a golden dandelion to lock the age forever (and again to unlock).
- Love mode: feeding a dog at full health makes hearts float above its head. If a tamed wolf
  nearby is in love too, it walks over and after a moment gives birth to a puppy owned by the dog player.
- Golden apples, enchanted golden apples and suspicious stew now apply their real effects to the dog.
- Bark keybind (default **V**) — dogs only, vanilla wolf sound. Being hit plays the vanilla wolf hurt sound too.
- The dog now has a real hitbox (0.6 × 0.85, puppies 0.3 × 0.425) that players and mobs can push against.
- Humans can now hit the dog; damage runs through the normal rules, so it can trigger the shared-death countdown.

**Changed**
- Hunger and saturation are gone: the hunger bar is hidden, there is no natural regeneration and
  no starvation. Health only comes back from food the owner hands over (2 × nutrition, same as
  vanilla wolf feeding).
- Dogs can sprint forever without saturation.
- Adult and puppy dogs both fit through one-block-high gaps.
- The dog uses vanilla wolf ambient/hurt sounds instead of human ones.

**Fixed**
- Looking at an enderman's eyes as a dog did not anger it.
- The human silhouette flashed for a frame when the dog crouched or stood up.
- Wolf armor could not be equipped by right-clicking the dog, and shears could not take it off.
- Wolf armor covered the dog's first-person view.
- With hitboxes shown (F3+B) the dog still could not enter one-block gaps — the server kept a
  stale 1.8-high size cache. It is now re-checked every tick.
- Mobs no longer target the dog out of nowhere; they retaliate only after the dog hits them.

**新增**
- 选完「当狗」后先选年龄（小狗 / 成年狗），再选狼变种；小狗 20 分钟后长大，
  喂金蒲公英可永久锁住幼犬形态（再喂一次解锁）。
- 寻爱：满血时被喂食会头顶冒爱心。附近若有同样在寻爱的驯服狼，它会走过来，
  过一会儿生下一只归属于狗玩家的小狗。
- 金苹果、附魔金苹果、谜之炖菜对狗生效，获得对应原版效果。
- 新增「狗叫」按键（默认 **V**），只有狗能用，播放原版狼叫；被打时也会播放原版狼的受伤音效。
- 狗拥有真正的碰撞箱（成年 0.6×0.85，幼犬 0.3×0.425），可以被玩家和生物挤压。
- 人可以攻击狗；伤害走原版流程，因此会触发死亡联动倒计时。

**改动**
- 删除饱食度与饱和度：饥饿条隐藏、不再自然回血、不会饿死；血量只能靠主人喂食恢复
  （每份食物回 2×营养值，与原版喂狼一致）。
- 狗无需饱和度即可无限疾跑。
- 成年狗与小狗都能穿过一格高的空间。
- 狗的叫声、受伤声改用原版狼音效，不再是人的声音。

**修复**
- 狗直视末影人眼睛时不再无法激怒末影人。
- 狗蹲下 / 起身的瞬间不再闪现人形。
- 狼铠可以右键给狗穿上，也可以用剪刀右键取下。
- 穿狼铠后不再遮挡狗的第一人称视野。
- 开启碰撞箱显示（F3+B）时狗仍进不去一格高的空间（服务端尺寸缓存停在 1.8 高），现已每 tick 自愈。
- 生物不再无缘无故把狗当目标，只有狗先动手才会记仇还击。
