If a transform need some args and config file, asbuild need to support these situations.

Wouldn't that be handled by args passed to asc, e.g. asb -- extraArg?

At present, transform wants to support configuration and can only let users set the configuration file path through environment variables. However, if transform can find the entrypoint file, it is more convenient to design an agreed configuration file path search, so even if asc currently does not support passing additional The configuration does not matter.
