* chore: apply go fix modernizers from Go 1.26
automated refactoring: interface{} to any, slices.Contains,
and other idiomatic updates.
* feat(ci): add `go fix` check to Go analysis workflow
ensures Go 1.26 modernizers are applied, fails CI if `go fix ./...`
produces any changes (similar to existing `go fmt` enforcement)
