DEVPROD-27645: Optimize lint-staged to only run schema check on GraphQL changes

[khelif96]

TLDR the check-schema-and-codegen lint task really annoyed me by being so slow so now it only runs on graphql changes

Summary

• Changed lint-staged config to trigger check-schema-and-codegen only on .graphql file changes instead of all TypeScript files
• Previously, the schema validation ran on every .ts/.tsx file change, which was inefficient since:
  • It makes a GitHub API network call on every commit
  • Runs full GraphQL codegen even for unrelated changes
  • CI already validates this with the check_codegen task

Test plan

• Verify lint-staged runs check-schema-and-codegen when modifying .graphql files
• Verify lint-staged does NOT run schema check when modifying only .ts/.tsx files

I'm not sure this is desirable if we're still going to run check_codegen on every job; this just delays the signal that your codegen needs updating which may be frustrating.

What do you think of also only running check_codegen when there are GraphQL changes? If this is successful, we could also remove it from the waterfall (but perhaps not just yet because that seems like removing a lot of signal at once).

Ok good point, How about 1 better and have a pr auto get created to bump types so that the types are always created and if someone takes a bit longer to merge their generated types every other user doesn't have to manually gen them
