Explore Federation v2 linting rules

[Urigo]

Is ti possible to create a lint rule for enforcing Fed v2?

This could help with subgraphs that needs to migrate and maybe provide some observability for the status of that kind of migration

Definitely possible

This lib is really hard to use in a federation project. We have all schema files spread out in packages, we want to lint them individually. And they are using a lot of federation directives, it feels like this should be a core feature of this lint package to support federation since almost all big projects use federation. And with Open Federation on the horizon... well ;)

I really dont want to specify/give hints on these things, the lib should pick it up via

schema
  @link(
    url: "https://specs.apollo.dev/federation/v2.4"
    import: [
      "@key"
      "@external"
      "@provides"
      "@requires"
      "@extends"
      "@shareable"
      "@tag"
      "@inaccessible"
      "@override"
    ]
  )

which federation imports are in place for the particular schema it is linting.

@klippx this was fixed in 4.3.0 #2812
