Narrative cases reported as "passed" — inflates pass count

[schgoo]

Problem

Cases with kind: narrative have no operation and no expected: list. The harness counts them as passing:

44 cases passed

But 5 of those 44 are narrative-only (documentation):

- name: edm_namespace_is_reserved
  kind: narrative
  desc: "The Edm namespace is reserved for OData primitive and abstract types..."

- name: date_types_use_proleptic_gregorian
  kind: narrative
  desc: "Edm.Date and Edm.DateTimeOffset use the proleptic Gregorian calendar..."

Their traces are empty (no traces) — there's nothing to validate.

Impact

"44 cases passed" suggests 44 behavioral validations ran. In reality only 39 actually tested anything. This misrepresents coverage.

Suggestion

Report separately:

39 cases passed, 5 narrative (no assertions)

Or add a CaseStatus::Narrative / CaseStatus::Skipped variant to distinguish them from actual test executions.
