Arena Regeneration System Rework

• Complete overhaul of the regeneration pipeline:
  • Restores blocks in order: Foundation ➜ Gravity ➜ Dependent
  • Physics are disabled during restoration to avoid block loss
  • Gravity blocks placed bottom to top to prevent falling
  • Auto-retries regeneration up to configurable max-retries
  • Regeneration runs even in unloaded chunks now!
  • Arena marked ready & available only after full regeneration
• Fully configurable via config.yml:
  
  Code (YAML):

  regeneration:
    batch-size : 1000
    max-retries : 5

️ Command & Duel Fixes

• Fixed duel request limitations — you can now send requests to multiple players
• /duel challenge <player> no longer blocked if you sent a request to someone else
• Improved internal request map & expiration handling
• Fixed ArrayIndexOutOfBounds errors in GUI menus & interactions

Arena Session Improvements

• Arena is only marked not in use after full regen is completed
• Added isReady() flag to track readiness state
• getRandomAvailableArena() now filters by !beingUsed && isReady
• Arena reload now safely restores all configuration & readiness state

Other Fixes & QoL

• Better debug logging during regeneration phases
• Reduced tick strain with batch-configurable regen
• Cleaner location serialization & loading with fallbacks
• Removed unsafe physics calls during async ops
