Vamooses Companions

ADDED:
- Companion sounds: Vamoose (Draenei female greetings), Scurry (3 squirrel
  variants with unique sounds), Gazlowe (classic + BfA goblin voice lines),
  Patches (full giant parrot sound set with wing flap). All extracted from
  WoW SoundKit DB2. Murgle's 12 murloc groups retain their existing sounds.
- Per-companion sound toggle: speaker icon in sidebar. Click to enable/disable
  sounds per companion. Defaults to off -- opt in per companion.
- Per-companion TTS toggle: TTS icon in sidebar above the speaker icon. Click
  to enable/disable text-to-speech per companion. Requires global TTS enabled.
  Defaults to off.
- TTS voice overrides per companion: Vamoose=Milena [ru-RU], Gazlowe=Grandpa
  [en-US], Murgle=Bubbles [en-US]. Other companions use the default TTS voice.
- Sound frequency gated by chattiness setting (globalCD 15-90s).
- Per-group intents system: all companions with modelGroups now have 16 explicit
  intents per group (IDLE through SLEEP + FIDGET), each mapping an animation
  slot and optional sound pool.

CHANGED:
- AnimDB behavior chains expanded with probed animations: CombatCritical, Stun,
  Attack1H, BattleRoar, Whirlwind, Talk, Work, Wave, Mount, and others added
  to humanoid, bird, and aquatic archetypes. Removed JumpStart from FALLING
  (broken 3-anim chain -- part of a start/jump/end sequence).
- Portrait sound resolver simplified: reads intents directly from modelGroups.
  No more INTENT_TO_SOUND/ANIM_TO_INTENT indirection.

FIXED:
- Achievement criteria collector used wrong API (GetAchievementInfo with a
  criteriaID instead of achievementID). Switched to CRITERIA_EARNED event
  which provides the correct achievementID.
- Legacy GetItemInfo() call in craft collector updated to C_Item.GetItemInfo().
