Updates the architecture/dependency diagrams and omissions table to match
what actually shipped: RemoteData<T> (not <E, T>), @angular/router moved
from "avoided" to "used", the new shared/infrastructure/http.ts fetch
boundary, and the CI/coverage gates now in place. Removes the now-false
"CI pipeline" omission row and adds honest rows for the linter and
per-environment config this template still deliberately skips.

README now shows folder layering, minimal-Angular dependency flow, and
the users feature data flow as diagrams. Adds docs/adding-a-store.md,
a step-by-step guide to building an Elm-style store from just signals.
