Fix Stage 3 issues based on Hermes feedback

- Add stage4_marketplace_economics to depends_on (AI operations need GPU listings from marketplace)
- Make ai_training_agent operation optional (gpu_listing may not exist)
- Add resource_depends field to training_schema.json for cross-stage resource dependencies
- Add ai_jobs check after ai_submit to verify job appears in listing
- Add finetune_status polling after finetune_submit for job monitoring
