Circle AppKit BridgeArc to EVM

Bridge

Move native USDC between Arc Testnet and supported EVM testnets. AppKit handles the CCTP burn, attestation, and relayed mint so the destination side does not need a manual mint transaction.

Bridge notes

AppKit Bridge currently moves USDC only.
The source wallet must hold USDC and the source chain's native gas token.
Circle's Forwarding Service submits the destination mint and deducts its fee from minted USDC.
The kit key is not required for this bridge flow; keep it in env only if we add swaps or paid kit features.
