v1.14.31 publish and validate both hit 'No space left on device' on single-arch amd64 smoke/validate builds. The image has crossed ~3 GB and the runner's ~40 GB overlay starts ~70% full, so 'load: true' peak disk (tarball + unpacked image + buildx cache) no longer fits. Add a 'Reclaim runner disk' step to validate-base, validate-omos, smoke-base, smoke-omos. Strips catthehacker-resident toolchains we never use (hosted-tool-cache, dotnet, android, powershell, swift, ghc, jvm, microsoft, chromium, boost), then runs 'docker system prune -af --volumes' + 'docker builder prune -af' against the runner's dockerd before setup-buildx-action. Expected reclaim is 6-12 GB depending on what's resident. Deliberately NOT in the per-arch matrix build jobs — push-by-digest doesn't need it and pruning in parallel jobs risks one job nuking another's in-flight buildx cache. Also add workflow-level concurrency on docker-publish.yml so concurrent tag pushes serialize cleanly.
