feat: add examples/demo.csv and examples/demo.improv

40-row CSV with obviously-fake sales data (fictional companies like
Acme Corp, Wonka Industries, Cyberdyne Systems). demo.improv generated
via headless import with Profit formula and a default view showing
Region+Product on rows, Date_Month+Measure on columns. Added the
import command to the README quick-start section.
