Refactor command registration to support guild-specific commands

- Updated the command registration process to allow for instant synchronization of guild commands, while maintaining global command registration.
- Introduced optional BOT_GUILD_ID environment variable for guild-specific command handling.
- Enhanced logging to differentiate between guild and global command registrations, improving traceability.
