Count Kubernetes mappings, not every parsed document.

If a chart template renders only null, js-yaml passes null to this callback. Line 317 counts it, so the staging check passes with no Kubernetes object. Require a non-null mapping, and add a null-only render test. The pinned parser’s loader includes parsed document results in the callback. (raw.githubusercontent.com)

As per coding guidelines, “New code path ≠ test: flag it. Name the specific test that should exist.”

Review comment at @.github/workflows/tests.yml at line 317:
Update the yaml.loadAll callback so objects counts only non-null mapping
documents, excluding scalars and arrays; add a null-only render test that
verifies the staging check fails when no Kubernetes mapping is rendered.
