Web3Signer class abstract

Abstraction for wallet signing.

Implement this to delegate signing to external wallets (WalletConnect, Secure Enclave, biometrics, etc.) without exposing privateKey to Web3WebView.

If you only need local private-key signing, use PrivateKeySigner or simply pass privateKey in Web3WalletConfig – the provider will wrap it automatically.
