Helm Validator

This is a structured, multi-stage validation pipeline for Helm charts that goes beyond basic linting. It runs ten sequential checks from chart structure through template rendering, YAML syntax, Kubernetes schema validation with kubeconform, CRD documentation lookups, and optional cluster dry-runs. The workflow is explicitly read-only by default and only modifies files when you ask it to apply fixes. It's designed to keep running after stage failures to give you a complete picture of all issues at once, which beats the typical fail-fast approach when you're debugging a messy chart. Useful before releases or when helm template mysteriously breaks. If you don't have cluster access, it skips the dry-run stage and documents why.
