PRODUCTION INFERENCE TEST

Tests the complete end-to-end distributed inference marketplace:
1. User submits request to marketplace
2. Marketplace assigns driver, locks price
3. User sends encrypted prompt to driver
4. Driver processes through distributed pipeline
5. Result returned to user
6. All nodes receive NEURO rewards via PoNW proofs
