Implement deduplicated schema format with definitions
Schema now stores each related model once in a 'definitions' object instead of duplicating it inline for every relationship. - Added getDeduplicatedSchema() method - Relationships reference models by class name - Definitions contain unique model schemas - 93% size reduction (1960KB -> 143KB for Associate model) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
