A fresh install opens to an empty space, so Smriti's value — which only
shows once reasoning has accumulated — is invisible on day one. `smriti
quickstart` seeds one small, finished project (a rate-limiting feature
built by two agents, with a branch explored and dropped) and prints a
short guided walkthrough.
The demo space `smriti-demo` carries a marker in its description: --remove
only deletes a marked space, --reset rebuilds it, and seeding rolls back a
half-built space on failure. The fixture is plain structured data with
content-integrity tests guarding counts, intent types, note kinds, the
demo marker, and branch divergence.
