Design doc for #508

Hi @ravjot07 😄

Good job! Let me provide more details.

This part has already undergone some development. We have designed a module called 'Checker' to perform checks for this section, and we have completed checks for aspects such as name, version, and checksum.

Checker is here: https://github.com/kcl-lang/kpm/blob/main/pkg/checker/checker.go

You can add your proposal with the following two points:

1. How do you plan to integrate the existing Checker into the current push functionality?

2. Please research other package management tools in the market, such as Cargo, Go Mod, or Helm, and find out what kinds of checks they perform.
