chore(changeset): declare the view filter operator input narrowing as Clause-② no (narrowing)

The diff narrows a published type and widens no accept set or public
surface, which scripts/pm/clause2-line.mjs spells `no (narrowing)`. The
minor level, the BREAKING banner, the FROM -> TO table and the ADR-0087
registered disposition are unchanged.

 The one-line fix: write the canonical id. Every alias maps to exactly one, and `VIEW_FILTER_OPERATOR_ALIASES` is that map; the rewritten rule selects the same rows, because the schema already folded the alias to that id.
