Subject: [PATCH] feat: add chainId 138 (DeFi Oracle Meta Mainnet)

Register DeFi Oracle Meta Mainnet (chain 138, DefiLlama dfio_meta_main) in the
static chain config so token info, swap, and risk commands can resolve chain 138
when paired with --rpc-url.

Includes live DODOApprove and ERC20V3Factory addresses deployed on chain 138.
Swap quotes still require DODO route-service support for chainId 138.

Closes #3
