New MCP tools: - basis_movement: aggregated basis trend, one headline line per crop. The cheap "how is basis moving overall" view; optional commodity/source/delivery/days. - basis_detail: per-(elevator, crop, delivery) basis first→last drill-down. Both do the aggregation MCP-side and return compact markdown to keep token burn low, so a client can call the cheap aggregate first and drill in only when needed. Flexibility/parity changes: - price_history: commodity is now optional (spans all crops); groups by (source, commodity, delivery); surfaces basis first→last in the summary and adds a futures column to the raw table. - latest_prices: expose the `kind` filter (grain/fertilizer) that the API and client already supported. - client.history(): commodity optional.
