Enhanced dual-wield logic

Browse Source 
Description of Changes:

    Implemented logic to ensure the strongest weapon is always placed in the main hand for dual-wielding or Titan Grip-capable bots.
    When equipping a new weapon, the code now compares the new weapon’s score with the currently equipped main-hand and off-hand weapons.
    If the new weapon is the strongest, it goes into the main hand. The previous main-hand weapon may be moved to the off-hand if it is allowed (e.g., not a main-hand-only weapon) and provides a performance improvement.
    Titan Grip conditions are accounted for, allowing valid two-handed weapons (2H axes, maces, swords) to be placed in the off-hand as well.
