[Azjol Nerub] Anub'arak's Adds have wrong spawn location and target player as they spawn

Current Behaviour

Anub'ar Guardian and Anub'ar Venomancer spawn on the web in front Anub'arak platform.

Adds target player as they spawn which can lead to Anub'ar Darter and Anub'ar Assassin dropping through the floor if their target is too far away.

Expected Behaviour

Anub'ar Guardian and Anub'ar Venomancer should spawn at the bottom sides of the stairs leading to Anub'arak.

Adds shouldn't target players as they spawn :

• Anub'ar Guardian and Anub'ar Venomancer should run to the front of Anub'arak platform as they spawn.
• Anub'ar Assassin should pick a random spot inside Anub'arak platform and jump to it.
• Anub'ar Darter seems to be spawning from the outside webs and under Anub'arak platform then goes up to reach a certain point above the platform then target a player and leap into them.

Wotlk Classic Heroic

• At 11:18 and 11:21 you can see they both Anub'ar Guardian are coming from left and right side from the bottom of the stairs then reach Anub'arak platform without targeting any player and same happens again at 12:14 and at 12:38 with Anub'ar Venomancer
• At 12:46, you can see Anub'ar Assassin dropping down outside on the left side of the player (you can see them under "Quêtes actives" in the player UI) then leap into a random spot inside the platform at 12:52 and 12:53

Wotlk Classic Heroic+

• At 8:33, you can see Anub'ar Assassin dropping down (it's slightly visible under the player buff bar) then leap into a random position inside Anub'arak platform
• At 10:31, you can see Anub'ar Darter flying from underneath Anub'arak platform then charge into a player

Wotlk Classic Heroic

• At 8:00, the warlock target one of the Anub'ar Guardian and you can see it has no target and you can see at the same time the other Anub'ar Guardian coming out of the other side of the stairs

Reproduce the Anub'arak encounter with .go c id 29120 and observe NPCs 29216, 29217, 29214, and 29213 during the submerge phase. Compare their spawn points, initial targeting, movement, and jumps with the linked WotLK Classic videos; done means each add follows the documented spawn and movement behavior without prematurely targeting players.
