- Unified Containerfile with cargo-chef and targets
      - Containerfile:1
      - Targets: builder (devtools), collector, nri-init
      - Includes rustfmt, clippy, cargo-chef, clang/libelf, and Helm for fast-tier checks.
  - Fast-tier workflow (fmt, clippy, unit tests, helm lint/template)
      - .github/workflows/ci-fast.yaml:1
      - Builds the builder image once and runs cargo/Helm inside it via docker run.
  - Reusable workflows (workflow_call) per integration area
      - Collector (GH-hosted assumptions + optional heavy S3): .github/workflows/reusable/test-collector.yaml:1
      - Resctrl (GH-hosted unit + optional e2e smoke on metal): .github/workflows/reusable/test-resctrl.yaml:1
      - Helm e2e (k3s + helm install, S3 smoke): .github/workflows/reusable/test-helm.yaml:1
      - NRI integration (GH-hosted k3s): .github/workflows/reusable/test-nri.yaml:1
  - Orchestrator workflow to wire everything and gate heavy tests by “level”
      - .github/workflows/ci-orchestrator.yaml:1
      - Builds collector and nri-init once (reusing Containerfile targets); then runs:
          - Fast checks (uses ci-fast)
          - NRI GH-hosted integration
          - Conditionally runs heavy suites (collector/resctrl/helm) based on level:
              - PRs: level cheap-short (heavy disabled)
              - Push to main: level full-long
              - Manual dispatch: selectable level
  - Updated existing build workflows to the new Containerfile
      - .github/workflows/build-component-artifacts.yaml:1
          - Uses Containerfile with target: collector|nri-init
      - .github/workflows/build-collector.yaml:1
          - Triggers on Containerfile instead of Dockerfile.* and keeps multi-arch manifest

complete migration and retire old flows

… we run it in its own job anyway
