📝 Walkthrough

Walkthrough

This PR introduces a complete Helm chart for Portabase Agent, enabling containerized Kubernetes deployments. It adds GitHub Actions workflow automation to publish charts to OCI registry, along with Helm templates (ConfigMaps, Deployment) and default values configuration for environment variables, resources, and optional config file mounting.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflows .github/workflows/helm.yml, .github/workflows/release.yml	New Helm chart publishing workflow triggered by release pipeline; publishes packaged charts to ghcr.io/portabase/charts as OCI artifacts. Release workflow updated to invoke publish-helm job before finalize-release and notify-discord.
Helm Chart Metadata helm/Chart.yaml, helm/.helmignore	Chart descriptor defining Portabase Agent v0.0.0 with maintainers, keywords, and repository metadata. Helmignore file excludes common VCS, editor, and system files from packaging.
Helm Templates helm/templates/deployment.yaml, helm/templates/configmap.yaml, helm/templates/env-configmap.yaml	Deployment template with conditional hostPath or ConfigMap-based config.json mounting, configurable replicas, image settings, and host aliases. Two ConfigMaps for environment variables and optional configuration file content.
Helm Configuration & Documentation helm/values.yaml, helm/README.md	Default values providing image repository (portabase/agent), environment variables (EDGE_KEY, TZ, POLLING, APP_ENV, LOG), resource limits, and inline database configuration. README adds development notes with kubectl and helm commands for local testing and management.

🐰 A chart for the agent to sail
Through Kubernetes clouds without fail,
