📝 Walkthrough

Walkthrough

The change removes fixed years from SPDX copyright notices across repository metadata, license templates, production Go files, generated code, tests, and integration files. One test file also receives SPDX copyright and Apache-2.0 license headers.

Changes

License header migration

Layer / File(s)	Summary
Header policy and templates CLAUDE.md, REUSE.toml, hack/*	Documentation, REUSE annotations, and license templates use year-free SPDX copyright text.
Production source headers api/v1alpha1/*, cmd/*, cmdutils/*.go, internal/*, server/*.go	Production and generated Go files remove fixed years from SPDX copyright headers.
Test and integration headers cmdutils/*_test.go, internal/**/*_test.go, server/*_test.go, test/*	Test and integration files remove fixed years. internal/uki/oci_test.go receives SPDX and Apache-2.0 headers.

Priority: ⬇️ Low — Defer this license-header cleanup because it is a low-effort, non-functional metadata change with no product behavior impact.
