feat(melonx): new melonx commands

Introduced new commands to the MeloNX cog: mods, gamecrash, requirements, error, and 26 (iOS 26), each with their own handler and help embed. Updated the README and melonx.py select menu to reflect the new commands. These additions provide users with troubleshooting and informational commands for common MeloNX issues and topics.
