Performance & Lag Fixes for 4+ Players

• Kick Anti-Spam & Cooldowns: Added a 250ms per-player and 100ms global ball cooldown to prevent physics and sound flooding when multiple players scrum for the ball.
• Eliminated World-Wide Entity Scans: Removed recursive full-world entity searches on ball removal and hologram updates during matches, relying on direct reference disposal.
• Cached Geometry: BoundingBoxes for goals and arena boundaries are now cached in-memory instead of reparsing YAML configuration files 300 times per second in the tick loop.
• Throw-in Clamping: Ball is placed 1 block inside the field on throw-ins, preventing infinite out-of-bounds loops.
• Collision Optimization: Disabled LivingEntity collision on the ball stand to prevent O(N^2) player pushing loops.
• Asynchronous Stats: Disk writes to stats.yml now execute asynchronously off the main server thread.
• Mojang Skin Caching: Pre-cached player skull to prevent synchronous HTTP lookups on ball respawns.
