refactor(query-core): drop NoInfer re-export, use built-in everywhere

Per @TkDodo's review: TypeScript's intrinsic NoInfer (TS ≥ 5.4) is the
canonical type, and the package already requires TS ≥ 5.4. Removing the
re-export sidesteps the self-shadowing issue entirely and avoids
encouraging consumers to import a duplicate.
