Subject: [PATCH] feat: add Radius Network support (eip155:723487)

Adds Radius Network (chain ID 723487) and Radius Testnet (chain ID 72344)
to the chains registry, following the pattern used for other EVM chains.

- Import `radius` and `radiusTestnet` from viem/chains (available since viem 2.48.0;
  the repo's `^2.39.3` range accepts it).
- Add entries to `chainMap`, `networkNameMap` (with `radius` / `radius-network` /
  `radiusnetwork` aliases for mainnet and `radius-testnet` / `radiustestnet` for
  testnet), and `rpcUrlMap`.
- Add both networks to the Supported Networks list in README.md.

Radius Network is a stablecoin-native EVM platform with ~500ms finality and
sub-penny gas. Registered in ethereum-lists/chains (#8168, merged).
