feat(format): lint formatting of a single file

[jameshearttech]

I use lint-staged in local development for linting files in Git staging prior to commit. I would like to lint package.json files using syncpack using the same approach. It would be great if I could do something like pnpm exec syncpack lint /path/to/package.json and it would override --source using the config from the root project in the monorepo.
