### Summary
- Add a preserveAuras flag to summon teleport helpers.
- Keep auras when using the summon command.
- Leave meeting stone behavior unchanged (auras can still be cleared
there).
### Motivation
Summon command was clearing buffs (e.g., Hellscream’s Warsong in ICC)
because auras were explicitly interrupted before teleporting. This
change keeps existing meeting stone behavior but preserves auras for the
summon path to avoid losing valid buffs.
