Feature request - Don't stop on the first error

[ezzatron]

With the CLI, It would be really nice to see all problems in one execution of npx @skypack/package-check. I was using the command to check up on some internal packages at my workplace, and there are some issues that I don't really intend to solve for our own internal stuff (e.g. keywords, TypeScript types). As soon as the first problem is detected, the command stops executing, so I can't easily tell if there are other issues that I can solve:

$ npx @skypack/package-check
✓ package.json
✓ ES Module Entrypoint
✓ Export Map
✓ No Unnecessary Files
✖ Keywords

$ _

The error code returned to the shell could be zeroed with an option (--dry-run or --check), so that the script can be run as part of a prepare step in package.json, without that step failing, if there were errors.
