Molecule AI Infra-SRE 2bb90a5b4b fix(CI): move changes job off self-hosted runner + add workflow concurrency ... Cherry-pick from staging PR #1194 for main. Two changes to relieve macOS arm64 runner saturation: 1. `changes` job: runs on ubuntu-latest instead of [self-hosted, macos, arm64]. This job does a plain `git diff` with zero macOS dependencies — moving it off the runner frees a slot immediately on every workflow trigger. 2. Add workflow-level concurrency: concurrency: group: ci-${{ github.ref }}; cancel-in-progress: true Prevents multiple stale in-flight CI runs from queuing on the same ref when new commits arrive.
