Add proper auth separation to HttpMcpProxy alongside the existing signer() path. The new authScheme() + identityResolver() + signerContext() builder API follows the canonical smithy-java auth architecture (AuthScheme + IdentityResolver + Signer separation) used by ClientPipeline. This enables direct use of SigV4AuthScheme and SdkCredentialsResolver for AWS-authenticated MCP endpoints without needing a custom adapter class. The existing signer() path remains unchanged for backward compatibility.
