Problem

lib/build-graph.py requires networkx but the agents Dockerfile only installs bare python3 (no pip, no packages). The structural analysis graph silently fails with ModuleNotFoundError: No module named 'networkx'.

This affects review-pr.sh, planner-run.sh, and predictor-run.sh — they all skip the graph and give Claude less context.

Fix

Add python3-pip and networkx to docker/agents/Dockerfile:

RUN apt-get update && apt-get install -y --no-install-recommends \
    bash curl git jq tmux cron python3 python3-pip openssh-client ca-certificates \
    && pip3 install --break-system-packages networkx \
    && rm -rf /var/lib/apt/lists/*

Or use the Debian package if available: python3-networkx.

## Problem `lib/build-graph.py` requires `networkx` but the agents Dockerfile only installs bare `python3` (no pip, no packages).
