chore(lint): migrate golangci-lint config to v2 + fix repo-wide findings

AYDEV-FR · AYDEV-FR · commit d6c5b0262686 · 2026-06-11T12:47:23.000+02:00
CI lint has been red on every branch since the action's 'latest'
moved to golangci-lint v2, which rejects the v1 config schema (and
the last v1 release can't even run against Go 1.26). Migrated with
'golangci-lint migrate', then tuned:

- exhaustive: default-signifies-exhaustive (all flagged switches
  already had an explicit default)
- drop goconst (pure noise: "true", "error", k8s condition strings)
- govet: disable shadow ('if err :=' inside an err scope is idiomatic)
- gocritic: disable hugeParam (controller-runtime passes specs by value)
- gochecknoinits excluded for api/ and cmd/ (kubebuilder scheme
  registration pattern), gocyclo excluded for Reconcile loops
- errcheck back to defaults (check-blank flagged deliberate discards)

Code fixes: gofmt x4, misspell x4, QF1008 embedded selector, named
results on JWTValidator.Validate, nolint on the scaffolded
scheme.Builder. golangci-lint v2.12.2 now reports 0 issues.
