Initial scaffold: @ng-eventually/client — SDK-shaped polyfill over NextGraph

Generic polyfill layer that makes a single NextGraph broker behave like the
not-yet-shipped multi-user NextGraph (emulated capabilities + inbox). Zero app domain.

@ng-eventually/client exposes an SDK-identical surface (ng, useShape, inbox); the
polyfill bootstrap (configure + capability helpers) is isolated under /polyfill, so
the main entry stays a drop-in for @ng-org/web|orm. The real SDK is injected at
configure() (no hard import → build-alias safe + testable).

Scaffold: NextGraph wiring stubbed with TODO; capability helpers implemented and
unit-tested (4 tests, typecheck clean). The global-index curator is deferred — in
NextGraph apps/services are mono-user with no global data.
