v3.0.0 - The RPG Gem System Update

SupperBackpack v3.0.0 introduces a massive overhaul to the gem system, transforming it from simple potion buffs into an engaging RPG-style ability system with crafting progression, single-active combo mechanics, and lag-free performance.

💎 Complete Gem System Overhaul

• 32 New RPG Ability Gems: Replaced old potion gems with highly specialized gems (e.g., Dash, Lifesteal, Magnet, Crafter).
• Rarity System (7 Tiers): Gems now scale from Common to Divine, with unique lore formatting, material costs, and particle effects.
• Crafting Progression: Added 32 new gem recipes. Upgrading a gem to Tier II now requires its Tier I version.

⚔️ New Active Combo Powers

• Single Active Combo Rule: You can now only have ONE combo active at a time (highest rarity combo takes priority).
• Each combo now grants a Passives + Active Ability (triggered by Sneak + Right-Click):
  • Dash (Parkour Set): Launch forward with 2s fall immunity.
  • Ore Pulse (Treasure Hunter): Highlight nearby ores behind walls for 5 seconds.
  • Blood Rage (Blood Warrior): Gain Strength II and 2x lifesteal chance for 6 seconds.
  • Water Surge (Ocean Explorer): Gain a massive dolphin-boost swimming propulsion.
  • Flame Burst (Nether Walker): Trigger a 3-block fire explosion that damages and ignites mobs.
  • Wind Lift (Sky Traveler): Automatically launch upward when squeezing sneak while falling.

🗺️ Visual & Quality of Life Improvements

• Revamped Combo GUI: /bp combos now displays required gems, active abilities, cooldowns, and a clear "ACTIVE COMBO" indicator.
• Tier 5 Backpack Removed: Streamlined tiers; Tier 4 (54 slots) is now the maximum upgrade.
• New Admin Command: Use /bpitem <gemType> to quickly obtain specific gems.

🛠️ Fixes & Technical Overhaul

• Blink Gem Fix: Blink teleportation now flawlessly ray-traces exactly where you look (including vertical angles) and ensures you only land in safe 2-block-tall air spaces.
• Magnet Gem Fix: Re-coded to strictly pull Dropped Items, preventing weird physics with XP orbs or arrows.
• Zero-Lag Event-Driven Architecture: Removed nearly all ticking tasks. The system now aggressively caches gem states per-player, updates only on inventory close/join, and uses timestamp tracking for abilities instead of Bukkit cooldowns. Everything runs instantly with zero TPS impact.
