test / test (push) Failing after 1m3s
Moves test.yml and release.yml off `runs-on: fish` (host) to an ephemeral rust:1-bookworm container on the podman runner: v4 built-in checkout (no Node), no host rustup, curl/jq installed in-container for the release upload. Keeps the bare host free of toolchain installs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
