The smoke-test app Dockerfiles ran `RUN npm install next@latest` right after
installing the pinned deps from package.json. This overrode the deliberate
`next` pin with a floating version (non-deterministic builds) and added a
flaky network round-trip that broke the agno smoke build with ECONNRESET on
2026-06-04 (run 26972381969). Every affected starter already pins `next` in
package.json (agno 16.0.7, adk 16.1.1, crewai ^15.5.15, llamaindex 16.0.8,
ms-agent-framework-python 16.0.8, pydantic-ai 16.0.7), so the extra install
is pure harm. Removing it makes builds deterministic and removes the network
fragility.
