Add an ApiClient method to obtain a client credentials (M2M) access token for server-to-server calls using the OAuth 2.0 client credentials grant. The method authenticates via HTTP Basic and caches the result in a configured token_store keyed by audience and scope set, so a repeat call within the token's lifetime skips the network round-trip. Add the ClientCredentialsTokenResult type and GetClientCredentialsTokenError, and document the method in the README and examples. Co-Authored-By: Claude <noreply@anthropic.com>
