Gabou's Libs

-Basic compat for replay mod

Changed

• Port to 1.21.11
• Increased the account-verification timeout to 60 seconds.

Fixed

• Corrected the Fabric and NeoForge Minecraft version dependencies.

• Added one safe same-nonce retry for delayed challenge packets.
• Fixed duplicate payload registration that caused 1.21+ NeoForge/Fabric clients to crash during startup.
