/**
 * Set-membership matcher: matches when the field equals any of `vals`. Use this instead of a
 * bare array in a query pattern — bare arrays are rejected by the matcher (a bare array is
 * ambiguous now that `vl` can hold a literal array value).
 *
 * Returns a `Set`, which the matcher engine checks via `.has` (O(1)). Members must be
 * primitives: `Set.has` is referential, so object/array members would silently never match —
 * we throw rather than fail silently. For object membership, use a predicate matcher, e.g.
 * `(v) => members.some(m => isEqual(v, m))`.
