Merge upstream/main into llama-runner-phase-0 — conflict in .github/workflows/test.yaml

AI Impact Summary

A v0.30.0-rc14 release is performing a merge of upstream/main into the llama-runner-phase-0 branch, signaling alignment with mainline changes. The merge introduced a conflict in the CI workflow file .github/workflows/test.yaml that must be resolved to restore reliable test execution. Resolving the conflict may require reconciling upstream test workflow steps with the llama-runner-phase-0 branch changes, which could affect test environments, runners, or matrix configurations. Until resolved, CI on this branch is at risk of instability, delaying validation and downstream release readiness for v0.30.0-rc14.
