Enhanced the feedback command's error response to use an embed for better user experience. Changed the 'user_id' parameter type from int to str in hackban commands to support non-integer user IDs.
Added a _require_group_prefix check to all hybrid commands in each cog to ensure commands are only executed when invoked with the appropriate group prefix. Also updated error handling in bot.py to silently ignore CheckFailure errors. This improves command organization and prevents accidental command execution outside their intended context.
Converted individual moderation command cogs (ban, kick, purge, warnings, archive, hackban, nick) into command factory functions and registered them under a new Moderation GroupCog in cogs/moderation/__init__.py. Updated bot.py and help.py to support the new moderation group and category. This improves organization and enables grouped moderation commands.
