The route/date analysis recipe currently fails when copied: its WHERE clause contains a comma after the route_id predicate. It also recommends materialized-view, which lib/stats_by_route_date.js explicitly rejects. Remove the comma and document the supported view option.

Validation at revision 74c1e81:

• Ran the original SQL against a controlled stats_by_route_date schema with DuckDB 1.5.6: Parser Error at the comma.
• Ran the corrected SQL against matching-route/in-range, different-route and out-of-range rows: only the intended row returned.
• Called the current createStatsByRouteAndDateView function with materialized-view: it raises “currently not supported”.
• Whitespace check passed. Documentation only; no import/runtime behavior changed. This check is a recipe reproduction, not a full GTFS import benchmark.
