Lint and reload / lint-and-reload (push) Failing after 2s
Validates YAML/required fields/duplicate ids/requirement types with yq+jq against the exact shape content.rs parses (not a full schema check - that would mean building portal just to lint content), then publishes portal.content.reload over NATS so every running portal instance picks up the change without a restart (portal's own content::watch_for_reload, added alongside this).
