JEPA On-Chain Distributed Weights Test

Tests the full pipeline:
1. Create and shard a JEPA model
2. Register model on ModelShardRegistry
3. Multiple storage providers announce shards
4. Verify shard availability
5. Retrieve and reassemble model
6. Run inference

Usage:
    # Start hardhat node first: npx hardhat node
    # Deploy contracts: npx hardhat run scripts/deploy.js --network localhost
