A shared generic across the LLMR method packages. It returns the small,
machine-readable set of health numbers behind a result object (the part you
would assert in a test or drop into a table), as distinct from report(),
which drafts methods-section prose.
Details
LLMR defines the generic and an erroring default only. The method packages (LLMRcontent, LLMRpanel) provide the implementations, each returning a tibble of the key numbers for its own result classes.
