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.

Add dedicated sections for the data model (formula examples), views and
axes (tile mode, records mode, drill-down), the .improv file format
(annotated example), import wizard and headless scripting, and the
command/effect architecture. Link docs/design-notes.md from the "Why"
section. Update build instructions to use `nix build .`.
