XP: Attribute Core

Improved stealth detection systems, Golden Guard, and area-of-effect heals, with stricter checks, fewer events per tick, and a more consistent mitigation/healing order.

Reworked Pet Mastery system, aura taunts, and aggro management: more stable threat, clear separation between hard taunts and numerical hate, and respect for immunities/bosses.

Optimized onPlayerTick() for PetMasteryEffect, TauntAuraEffect, and AggroForceHandler, reducing unnecessary calculations, improving target filters, and preventing overflows or abrupt target changes.

Reworked Blade Slash: unified trigger (attacks and air slash), lighter and more predictable projectile, and cooldown calculation based on attack speed and synchronized with the attribute system.
