fixes - auto slayer item equipping, max hit stun check

thanks for the great plugin. cut a build earlier and ran into some issues with auto slayer & auto eat, specifically in the water god dungeon. fixed 3 diff things in 3 diff commits:

• patched auto slayer to properly use the itemID property when doing item lookups for required equipment
• return the item ID from the currentEquipmentInSlot util
• update enemeyNextAttackCanStun to use the correct onhitEffects prop and access first array element w/ optional chaining to prevent property access issues. didn't fix the typo here as I didn't want to break any references I wasn't aware of

the MR is targetting dev. lmk if you want me to make any changes. mucho appreciated
