Add debugchannel Command for Plugin Message Debugging

Summary

This PR introduces the /grim debugchannel command, allowing users to inspect plugin message channels received by a specified player. It is useful for debugging custom payloads, Fabric channel registration, and other client-server communication aspects.

Changes

• New Command: debugchannel
  • Registered under grim|grimac
  • Requires permission: grim.debugchannel
  • Displays plugin channels a player has registered or interacted with
• Packet Listener:
  • Captures minecraft:register and minecraft:unregister messages
  • Maintains a map of player UUIDs to registered channels
  • Supports real-time updates and removal on player quit
• Localization Updates:
  • Added translations for debugchannel in all supported languages

Usage

/grim debugchannel <player>

Displays the plugin message channels registered by the specified player. If no player is provided, it defaults to the sender.

Impact

This command provides server administrators and developers with greater insight into player-client communication, aiding in debugging and cheat detection.

I made this PR on mobile that's why the commits are all over the place lol but you can see what files changed :D

Won't be merged not because this is a bad idea but the entire command system is being redone anyways so none of this will work.

I'll take a look after assuming you update it to fit the design.

[GigaZelensky]

Alright, I will take a look at the redone command system whenever it's out and will adapt the code accordingly.

debugchannels suggests that this is a command for developers, which is not the case. I suggest making the placeholder channels, and putting this in the profile command
