feat: add findings-to-recommendations traceability in codex analyze-with-file

Mirror the same Findings Coverage Matrix mechanism added to the Claude
version. Insert Step 4.1 between Intent Coverage (4.0) and Consolidate
Insights (now 4.2) to ensure all actionable findings are mapped to a
disposition before generating recommendations.
