This update for hauler fixes the following issues: Changes in hauler: - update to 2.0.1 (bsc#1269433, CVE-2026-48702): * bump go to 1.26.4 to squash CVE noise * Full v2 Release notes: https://github.com/hauler- dev/hauler/releases/tag/v2.0.0 - update to 2.0.0: * `v2.0.0` is a **major** release. It replaces Hauler's entire OCI plumbing... the ORAS v1 dependency and the in-house cosign fork with a native containerd based implementation, drops the deprecated `v1alpha1` API, and layers on a meaningful set of new capabilities and reliability fixes on top of that new foundation. * **Removed the ORAS v1 dependency** - push/pull is now driven directly by containerd's docker resolver and `google/go- containerregistry`, new `pkg/content/registry.go` (`RegistryTarget`) and `pkg/content/types.go` (`Target` interface, `IoContentWriter`) replaces what ORAS used to own. * **Removed the hauler-maintained cosign fork** - `pkg/cosign` is now a thin verify only wrapper around upstream `sigstore/cosign/v3`. Images are added through a native `s.AddImage()` path in `pkg/store` * **Added OCI 1.1 Referrers support** - signatures, attestations, and SBOMs are discovered both via the classic cosign tag convention (`sha256-.sig` / `.att` / `.sbom`) and the modern Referrers API, then correctly through the OCI layout - update x/net to v0.55.0 (bsc#1266602, CVE-2026-39821, bsc#1267150, CVE-2026-25680, CVE-2026-42502, CVE-2026-27136, CVE-2026-25681, CVE-2026-42506)
