Implements a complete dimensional model in the Gold layer for cross-domain health analytics. 10 dimension tables (date, time_of_day, health_zone, source, body_system, metric, workout_type, meal_type, lab_marker, supplement) and 8 fact tables/views (daily_health_score, heart_rate_summary, sleep_session, workout, daily_nutrition, body_measurement, lab_result, daily_vitals_summary). DuckDB-native SQL with exclusive upper bound convention for zone joins. Verified against dev database with real data. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
