ci: port arm 32-bit job
Co-authored-by: Max Edwards <youwontforgetthis@gmail.com>
What changed, and why it matters
This commit adds a new automated testing job for 32-bit ARM processors in Bitcoin Core's GitHub Actions CI workflow. It does not change any wallet, networking, consensus, or node code that end users run. It only affects internal continuous integration (CI) infrastructure.
No security action required. Review as normal CI/infrastructure maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff adds a ci-matrix job to .github/workflows/ci.yml that runs the existing ./ci/test/00_setup_env_arm.sh environment script on ubuntu-24.04-arm runners. It reuses existing internal composite actions (checkout, configure-environment, restore-caches, configure-docker, save-caches) and the existing ./ci/test_run_all.sh entry point. No application source code, build scripts consumed by users, secrets, permissions, or network-facing configuration are modified.
