Jordan Ritter b9bcf2e6b6 fix(showcase/packages-python): drop to USER app across 11 Python packages, add missing /app/public COPY to langgraph-python
All 11 Python runners previously executed as root. Bring them into parity
with langroid (the one Python package that already had the pattern):

- Create uid/gid 1001 'app' user/group before any COPY
- Add --chown=app:app to runner-stage COPY directives
- USER app before EXPOSE/CMD
- langgraph-python: add the missing COPY --from=frontend /app/public line
  (every other Python package has it) plus an empty public/.gitkeep so
  the copy resolves

Packages touched: ag2, agno, claude-sdk-python, crewai-crews, google-adk,
langgraph-fastapi, langgraph-python, llamaindex, ms-agent-python,
pydantic-ai, strands.

# build-essential, dev headers needed to compile wheels that don't ship
# pre-built for ``-slim``) and produces a self-contained ``/opt/venv`` that
# the runner COPYs in as a single opaque tree. The runner never runs
# ``pip install`` itself, so no compiler toolchain bloats the final image.

# Next.js invocation only so non-Next children see the host's environment.
