Add the queryKnobs field to query_settings.idl referencing QuerySettingsKnobOverlay as an IDL custom type. Wire the hasher into QuerySettings::hash_value(). Bump the 3 static_assert field-count guards (QuerySettings, QueryShapeConfiguration, QueryShapeConfigurationRoundTrip). No merge logic, no validation beyond what fromBSON() already does. Merge semantics are handled in a follow-up ticket.
