Implements the top-level httpx.Client that composes the full chain: Logging → User Middlewares → Retry → Circuit Breaker → Balancer → Transport - Response wrapper with JSON/XML/Bytes decoding and body caching - NewJSONRequest helper with Content-Type and GetBody support - Functional options: WithBaseURL, WithTimeout, WithRetry, WithEndpoints, etc. - Integration tests covering retry, balancing, error mapping, and JSON round-trips
