OCR transformations, BaseOcrConfig with its response and connection types,
the OCR error, and the HTTP pieces (custom_httpx: http_handler, transport,
media, llm_http_handler with OcrClient and the request/response handler)
now live in litellm-llms at their Python paths. Provider code no longer
reaches into the route: it gets the caller's hooks through a route-neutral
CallHooks trait that core implements over its host, and core dispatches to
llm_http_handler::ocr with the concrete config, the way Python calls
base_llm_http_handler.ocr(provider_config=...).
Core keeps the route: entrypoint, request types, credential fallback,
provider dispatch, the machine and hook glue. ocr/mod.rs no longer
re-exports anything, provider constants moved next to their only users,
and provider tests that drive the whole route moved to core's route test
files. Twenty-two of those were exact copies of tests already there and
were dropped; every one still runs once.

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.
