• Error Handling: Chain-specific error messages

Usage Examples:

# Get blocks from specific chain
aitbc client blocks --chain-id ait-devnet --limit 10

# Default behavior (backward compatible)
aitbc client blocks --limit 10

Output Format:

{
  "blocks": [...],
  "chain_id": "ait-devnet",
  "limit": 10,
  "query_type": "single_chain"
}
