Cool Auth

Critical Fixes

• Fixed Startup Crash: The /changepassword command was missing from plugin.yml, which caused a NullPointerException on server start.
• Fixed Main Thread Lag: Database updates (updatePlayerInfo) during login are now processed Asynchronously. This stops the server from freezing when a player joins.
• Fixed MySQL Timeouts: Added an ensureConnection() check. The plugin now auto-reconnects to the database if the connection was idle for too long (fixing the "8-hour bug").

New Features

• Configurable Encryption: Added encryption_type to config. You can now choose between OWE (One-Way Hashing / SHA-256) for max security or TWE (Two-Way Encryption / AES) for password recovery.
• Better "Frozen" State: Optimized the PlayerMoveEvent listener. Unauthenticated players can now rotate their heads (look around) but cannot walk (X, Y, Z locked). This prevents the glitchy "rubber-banding" effect.

Technical Changes

• Version Sync: Aligned pom.xml and plugin.yml to version 2.0.2.
• Safety Checks: Added a warning if TWE is selected but the secret key is not 16 characters long.
