Implements `transfer_remote` and `quote_transfer_remote` actions so AgentKit agents can bridge ERC-20 tokens between EVM chains via Hyperlane Warp Routes. Origin chains supported: Base, Ethereum, Optimism, Arbitrum mainnets. Destinations are resolved by name (ethereum, optimism, base, arbitrum, polygon, bsc, etc.) to canonical Hyperlane domain IDs from the hyperlane-registry. The transfer flow reads decimals from the underlying ERC-20, checks balance, quotes interchain gas via the Warp Route's quoteGasPayment, approves the Warp Route to spend the token, then dispatches transferRemote with the quoted gas attached as msg.value. Closes coinbase#1142.

Description
Closes #1142.
Adds a Hyperlane action provider so AgentKit agents can bridge ERC-20 tokens cross-chain via Hyperlane Warp Routes.
Two actions:
transfer_remote— approves the Warp Route, readsquoteGasPayment, dispatchestransferRemotewith the quoted amount asmsg.value.quote_transfer_remote— readsquoteGasPaymentfor a preview.Origin chains supported: Base, Ethereum, Optimism, Arbitrum mainnets. Destinations are resolved by name (ethereum, optimism, base, arbitrum, polygon, bsc, etc.) to canonical Hyperlane domain IDs from the hyperlane-registry.
Follows the
AaveActionProviderlayout from #865 (provider, schemas, constants, utils, README, changelog, unit tests with a mockedEvmWalletProvider).TypeScript provider will follow in a separate PR.
Tests
Unit tests: 14/14 passing.
Coverage:
supports_network, destination domain resolution (case-insensitive + unknown chain), schema validation, transfer happy path (assertsmsg.valuematches the quoted gas), unsupported origin, unknown destination, insufficient balance early-exit, quote action.Lint / format:
make lintandmake formatclean on the added files.Live test: Pending. Happy to verify end-to-end with a small Base→Optimism or Base→Arbitrum USDC Warp Route transfer once a maintainer is reviewing — will paste the tx hash + Hyperlane Explorer link in a follow-up comment.
