Subject: [PATCH 2/2] Fix test workflows to download artifacts and use local
 action

- Add needs: [build_binaries] to all test jobs that use the action
- Replace remote action references with local (uses: ./)
- Add checkout step where missing
- Add artifact download and distribute directory setup before action usage
- This ensures binaries built by build_binaries job are available when tests run
