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

Add Phase 4 Step 2 "Findings Coverage Matrix" to ensure all actionable
findings from analysis rounds are mapped to a disposition (recommendation,
absorbed, deferred, or informational) before consolidation. This prevents
the issue where rich analysis discovers many actionable points but only
a subset makes it into final recommendations.
