Hakari Jackpot Slot

• Added a Hakari-inspired slot machine item (Hakari's Jackpot Slot) that players can right-click to roll for a 15% jackpot. On a win, it grants 4 minutes 11 seconds of invulnerability plus heavy buffs (Strength V, Resistance IV, Regeneration III, Absorption hearts, Speed II, Fire Resistance).
• Jackpot invulnerability is tracked server-side and restored every tick during the duration; it safely reverts to the player's prior invulnerability state when time expires.
• Losing spins give brief nausea and slowness to sell the miss.
• Claim the item with the /hakari command or find it in the Combat creative tab.
• The item uses a nether star look; no custom texture is required.
• Note: The mod enforces invulnerability during jackpots, which may conflict with other mods that toggle the same flag; jackpot duration does not persist across server restarts.
