Subject: [PATCH] feat: add Aurigraph Mainnet (8471) and Aurigraph Testnet
 (8472)

Two new EIP-155 chain entries for the Aurigraph DLT V12 EVM-compatibility
layer.

- Aurigraph Mainnet (8471 / AUR): production chain, mainnet RPC + explorer
- Aurigraph Testnet (8472 / tAUR): public testnet with faucet at
  https://faucet-testnet.aurigraph.io

Both networks expose standard Ethereum JSON-RPC; native AUR is a fresh
token (not bridged from any other chain). Block time ~500ms,
deterministic finality after 3 blocks under HyperRAFT++ consensus.
Features: EIP155 (replay protection via chainId) + EIP1559 (base-fee gas).

Chain IDs verified unregistered at https://chainid.network on 2026-04-30.
Validated locally: ./gradlew run BUILD SUCCESSFUL.
