Yujong Lee 904c679595 refactor(rust): add types and core-utils crates, unify the provider error ... litellm-types mirrors litellm/types (chat, Anthropic Messages and Responses websocket data) and litellm-core-utils mirrors litellm/litellm_core_utils (provider resolution, prompt factory, core helpers, call arguments). Route request types move up to their core route module, the transform contracts move into base_llm, and the three duplicated provider error enums become one Error in base_llm/chat/transformation.rs, mirroring BaseLLMException. The empty-text placeholder goes back to the value Python's factory.py uses; the provider extraction had changed it to a single space.
