feat: add a.DI helper#53

Conversation
Adds a Foundry test helper for Aave Delivery Infrastructure that composes pigeon's existing CCIP, LayerZero V2, and Hyperlane helpers plus a new ArbitrumNativeHelper primitive. Two entry points cover the shipping a.DI lanes: helpEthToArb relays through the Arbitrum native inbox (decoding the packed retryable, pranking the Inbox-aliased L1 sender on L2), and helpMultiBridge relays through any subset of CCIP/LZ V2/Hyperlane on a multi-bridge consensus lane. The ArbitrumNativeHelper is a standalone primitive reusable for any L1 contract that wraps Inbox.createRetryableTicket. Funding the CCC is the test author's responsibility; the helper does not fund. Tests run against real Eth+Arb forks with the Aave Labs forked deployment.

Adds a Foundry test helper for Aave Delivery Infrastructure (a.DI). The
AdiHelpercomposes pigeon's existingCcipHelper,LayerZeroV2Helper,HyperlaneHelper, and a newArbitrumNativeHelperprimitive, exposing two entry points:helpEthToArb(Arbitrum native inbox — decodes the packed retryable, pranks as the Inbox-aliased L1 sender on L2, calls the receiver) andhelpMultiBridge(any subset of CCIP/LZ V2/Hyperlane for a multi-bridge consensus lane such as Arb→Eth or future Arb→Op). TheArbitrumNativeHelperis reusable beyond a.DI for any L1 contract wrappingInbox.createRetryableTicket. Funding the CCC for AMB fees is the caller's responsibility — the helper does not fund. Tests run against real Eth+Arb forks against the Aave Labs forked a.DI deployment.Stacked on #51 (
feat/ccip-helper).
