feat(client): complete SDK-shaped surface — init/initNg + SDK type re-exports

lifecycle.ts forwards init (@ng-org/web) and initNg (@ng-org/orm) to the injected
SDK; index re-exports the SDK types (ShapeType, BaseType, Schema, DeepSignalSet, NG) so
consumers import everything from @ng-eventually/client. Type re-exports are erased at
build → no runtime @ng-org import added (no duplicate SDK copy). @ng-org added as
devDependencies (typecheck only) + peerDependencies. EventuallyConfig accepts init/initNg.
Typecheck + 4 tests green.
