Add forbidigo linter to enforce cmp.Equal usage

jferrl · jferrl · commit e7ab55371b05 · 2025-08-19T09:26:55.000+02:00
Configured the forbidigo linter in .golangci.yml to forbid the use of reflect.DeepEqual, recommending cmp.Equal instead. This helps ensure more reliable equality checks in the codebase.
