feat: Add support for arm64 architecture (#11)
* feat: Add support for arm64 architecture

This commit introduces support for the arm64 architecture by:

1.  **Updating the Dockerfile:**
    *   The `exporter/Dockerfile` now uses the `TARGETARCH` build argument to dynamically determine the correct path for `libiperf.so.0`. This allows the same Dockerfile to be used for building both `amd64` and `arm64` images.

2.  **Modifying GitHub Workflows:**
    *   The CI workflow (`.github/workflows/ci.yaml`) and the Release workflow (`.github/workflows/release.yml`) have been updated to build and push multi-architecture Docker images (`linux/amd64` and `linux/arm64`).
    *   This involves adding the `docker/setup-qemu-action` for cross-compilation and specifying the target platforms in the `docker/build-push-action`.

3.  **Helm Chart:**
    *   No changes were required for the Helm chart as the image tag will now point to a multi-arch manifest, and the default iperf3 server image (`networkstatic/iperf3:latest`) is assumed to be multi-arch. Node selectors in the chart are not architecture-specific.

These changes enable the deployment of the iperf3-monitor on Kubernetes clusters with arm64 nodes.

* fix: Ensure multi-platform builds with Docker Buildx

This commit updates the GitHub Actions workflows to correctly set up
Docker Buildx for multi-platform (amd64, arm64) image builds.

Previously, the workflows were missing the `docker/setup-buildx-action`
step, which led to errors when attempting multi-platform builds as the
default Docker driver does not support this.

The following changes were made:
1.  **Added `docker/setup-buildx-action@v3`:**
    - This step is now included in both the CI (`.github/workflows/ci.yaml`) and Release (`.github/workflows/release.yml`) workflows before the QEMU setup and build/push actions.

2.  **Dockerfile (`exporter/Dockerfile`):**
    - Remains as per the previous commit, using `TARGETARCH` to correctly copy architecture-specific libraries. This part was already correct for multi-arch builds.

3.  **Helm Chart:**
    - No changes were required for the Helm chart.

This ensures that the CI/CD pipeline can successfully build and push
Docker images for both `linux/amd64` and `linux/arm64` architectures.

* fix: Correct Dockerfile lib path and add Helm dependency toggle

This commit includes two main changes:

1.  **Fix Dockerfile library path for amd64:**
    - I updated the `exporter/Dockerfile` to correctly determine the source path for `libiperf.so.0` when building for different architectures.
    - Specifically, for `TARGETARCH=amd64`, the path `/usr/lib/x86_64-linux-gnu/libiperf.so.0` is now used.
    - For `TARGETARCH=arm64`, the path `/usr/lib/aarch64-linux-gnu/libiperf.so.0` is used.
    - I achieved this by copying the library to a canonical temporary location in the builder stage based on `TARGETARCH`, and then copying it from this location into the final image. This resolves an issue where builds for `amd64` would fail to find the library.

2.  **Add Helm chart option to disable dependencies:**
    - I added a new option `dependencies.install` (default: `true`) to `charts/iperf3-monitor/values.yaml`.
    - This allows you to disable the installation of managed dependencies (i.e., Prometheus Operator via `kube-prometheus-stack` or `prometheus-operator` from TrueCharts) even if `serviceMonitor.enabled` is true.
    - I updated the `condition` for these dependencies in `charts/iperf3-monitor/Chart.yaml` to `dependencies.install, serviceMonitor.enabled, ...`.
    - This is useful for you if you manage your Prometheus Operator installation separately.

Malar Invention f3968a609e feat: Introduce iperf3 Kubernetes network monitor
Add core components for continuous cluster network validation:
- Python exporter (`exporter/`) to run iperf3 tests and expose Prometheus metrics.
- Helm chart (`charts/iperf3-monitor/`) for deploying the exporter as a
  Deployment and iperf3 server as a DaemonSet.
- CI/CD workflow (`.github/workflows/release.yml`) for building/publishing
  images and charts on tag creation.
- Initial documentation, license, and `.gitignore`.
