Release workflow: fix git dubious-ownership failure in “Release artifacts and AUR”

[Copilot]

The release pipeline was failing in the Release artifacts and AUR job when make checksums invoked git archive inside the Arch container. Git rejected the workspace as an unsafe repository (detected dubious ownership), stopping artifact generation and downstream AUR steps.

• Root cause

  • The containerized release job did not guarantee safe.directory configuration before running git-based packaging commands (dist/checksums).

• Workflow change

  • Added an explicit post-checkout step in .github/workflows/release.yml to mark the Actions workspace as safe for git operations in this job.
  • This ensures git archive and other git commands used during release artifact creation run consistently under the container’s ownership model.

• Scope

  • Single-file, minimal workflow update.
  • No changes to release scripts, Makefile targets, or package metadata logic.
