Problem

The Dev Container image does not include the helm CLI. This prevents users from running helm lint, helm template, or deploying charts from within the container — which is a common workflow when working on Kubernetes projects (including this repo's own chart).

Expected Behavior

helm should be available in the container's $PATH so users can:

Lint and template Helm charts during development
Deploy/upgrade releases from within the dev environment
Use helm in CI validation steps run inside the container

Proposed Solution

Add Helm installation to the Dockerfile, e.g.:

RUN curl -fsSL https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

Or pin a specific version:

ARG HELM_VERSION=3.17.1
RUN curl -fsSL "https://get.helm.sh/helm-v${HELM_VERSION}-linux-amd64.tar.gz" | \
    tar -xz --strip-components=1 -C /usr/local/bin linux-amd64/helm && \
    chmod +x /usr/local/bin/helm

Pinning is preferred to match the project's move toward reproducible builds (see Phase 0 changes in c8a7bbc).

Context

Discovered while attempting to run helm lint from within the dev container to validate chart changes.
