Make sure to update DuckDB to v2.0 first!

Example workflow: ATTACH 'differential:sales' AS sales; CREATE TABLE sales.t AS SELECT 42 AS v; CALL differential_create_snapshot('sales'); UPDATE sales.t SET v = 99; SELECT v FROM sales.t AT (VERSION => 1); -- 42 Same SQL conventions as DuckLake. Experimental, Linux and macOS.
