cargo component serve does not show in cargo component --help

cargo component serve does not show in cargo component --help and this is because serve isn't a directly supported cargo-component command, like:

cargo-component/src/bin/cargo-component.rs

Lines 67 to 76 in 5063442

    
           enum Command { 
        
               Add(AddCommand), 
        
               // TODO: Init(InitCommand), 
        
               New(NewCommand), 
        
               // TODO: Remove(RemoveCommand), 
        
               Update(UpdateCommand), 
        
               Publish(PublishCommand), 
        
               // TODO: Yank(YankCommand), 
        
               // TODO: Vendor(VendorCommand), 
        
           }

And, instead, it is a cargo command (not really, but, as per the code's nomenclature, yes):

cargo-component/src/lib.rs

Lines 74 to 83 in 5063442

    
           enum CargoCommand { 
        
               #[default] 
        
               Other, 
        
               Help, 
        
               Build, 
        
               Run, 
        
               Test, 
        
               Bench, 
        
               Serve, 
        
           }

I think it would be helpful to add serve as a proper cargo-component command for discoverability of the feature*.

When I added serve I just treated it as a special case of run. That’s why it’s in CargoCommand instead of Command.

I didn’t know that CargoCommands don’t get help support. Maybe this should be added for all of them, not just serve. It seems a bit strange that --help doesn’t list all commands available. A user has to guess that cargo component has for example its own run command, but fmt is just propagated. The current --help makes it seem like all subcommands except for the ones in the Command enum are propagated.
