Fixed:
- Defile on others no longer shows tank name
- Uses DBM-style target scanning (wait for boss to switch)
- Works on Warmane, TrinityCore, and all private servers
- 400ms scan timeout (silent fail > wrong name)
Kept:
- DBM voice countdown (5 sec before Defile)
- CLEU destName/destGUID fast paths (instant if server provides)
