docs(changeset): declare Clause-② yes (narrowing), since three type names are added

The diff narrows published types and also adds three exported names
(JoinedReportBlockParsed, ViewItemParsed, ViewItemWireParsed), so the line
reads `yes (narrowing)`. The BREAKING banner and the ADR-0087 marker reason
now say that no EXISTING export changes; the marker token is unchanged.

 fix(spec): `JoinedReportBlock`, a ViewItem's `config` and a flattened overlay's `viewKind` carry the shapes their doors accept (#19920)

-**BREAKING for TypeScript code that annotates with `JoinedReportBlock`, `Report`, `ReportParsed`, `ViewItem`, `ViewItemWire`, `ViewMetadata`, `ViewMetadataParsed`, `AssembledViewArtifact` or `AssembledViewArtifactParsed`, or that passes an unchecked value to `defineReport` / `defineViewItem`**: a narrowing of published TYPES, landing in the launch window as `minor` (the lockstep convention: the bump level is not the carrier, this banner and the disposition below are). The runtime accept set does not move at all: no schema's parse, no export and no value changes.
