📝 WalkthroughWalkthroughAdds comprehensive Stellar blockchain support including SEP-10 authentication, Soroban contract interactions, and multi-chain address handling. Refactors EVM-only abstractions into a multi-chain ChainAdapter pattern, redesigns authentication to be chain-aware with separate EVM and Stellar services, introduces Stellar-specific cryptographic utilities and address conversions, and extends test infrastructure with Stellar deployment and integration test support.
