The GitHub Actions definitions contained duplicated code for building the container image. This change introduces a reusable workflow in .github/workflows/reusable-build.yaml that encapsulates the common steps (checkout, install dependencies, and build). Both build.yaml and build_and_push.yaml now call this reusable workflow, which reduces duplication and improves maintainability while preserving existing functionality.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

This step is not shared between the workflows, so please do not include it in the shared reusable-build workflow.

Thank you for the feedback. I've refactored the solution to use a composite action for the shared build steps (Checkout, Install qemu, Build Image) instead of a reusable workflow. This allows the 'Push To Registry' step to remain in the build_and_push.yaml workflow where it is needed, while still eliminating code duplication for the common parts.

- Created `.github/actions/build-image/action.yml` to encapsulate shared build steps.
- Updated `build.yaml` and `build_and_push.yaml` to use the new composite action.
- Kept the "Push To Registry" step in `build_and_push.yaml` as it is not shared.
- Deleted the previously created `reusable-build.yaml` workflow.
- Created `.github/actions/build-image/action.yml` to encapsulate shared build steps (qemu setup, image build).
- Updated `build.yaml` and `build_and_push.yaml` to use the composite action.
- Ensured `actions/checkout` is run before calling the local composite action in both workflows.
- Kept the "Push To Registry" step in `build_and_push.yaml` as requested.
- Merged `build.yaml` and `build_and_push.yaml` into a single `.github/workflows/build.yaml`.
- Used conditional logic for the "Push To Registry" step to only run on tag pushes.
- Implemented dynamic tagging (SHA for PRs, tag name for pushes).
- Removed redundant workflow and composite action.

Looks great! Can you please remove the meaningless commits so that there is a single commit with a meaningful commt message?

Understood. I will squash all previous changes into a single, meaningful commit that consolidates the GitHub Actions workflows, as requested.

Consolidate the duplicated logic from `build.yaml` and `build_and_push.yaml`
into a single workflow at `.github/workflows/build.yaml`.

- Combined `pull_request` and `push tags` triggers.
- Implemented dynamic tagging (SHA for PRs, tag name for releases).
- Added conditional execution for the "Push To Registry" step.
- Removed redundant workflow and actions.

Acknowledged. I am ensuring that the Pull Request will contain exactly one commit with a meaningful message by squashing all previous changes into the final submission.
