Package config loads scripts/devbase.yaml, the per-repo configuration file consulted by devbase lint graphql for exclude patterns and per-rule severity/option overrides.

Package gitdiff resolves the merge-base commit between HEAD and a base ref using go-git, then reads file content from that commit's tree.

Package lint runs the Tier 1, Tier 2, and (so far, partially) Tier 3 rule tiers against a repository's *.graphql files.
