Summary

• Make the Helm chart installable on Kubernetes by default, with optional Ingress, OpenShift Route, and ServiceMonitor.
• Keep one values.yaml, one replica, and the existing HPA, PDB, and NetworkPolicy switches disabled by default.
• Set chart, application, and lockfile source versions to the latest release, v5.0.0.
• Update semantic-release to write matching source versions and build the versioned image after the version update.
• Rewrite the chart README with Kubernetes and OpenShift deployment examples.

Validation

• Ruff, mypy, 26 pytest tests, and uv lock --check passed.
• Helm lint, package, and template checks passed for the default, Route, Ingress, and ServiceMonitor configurations.
• The packaged chart renders ghcr.io/ehsanmsb/mkdocs-mcp:5.0.0.
• Local Docker build could not run because the Docker daemon is stopped; PR CI includes a Docker build.
