Settings sources beyond HTTP (media fetch, Azure Document Intelligence,
Vertex, timeouts) need the same env lookup and precedence merge, so move
them out of litellm-http into core_utils::settings. Lookup readers name the
Python idiom they mirror: get keeps a present empty value like
os.getenv(X, fallback), truthy drops it like an `or` chain, enabled only
switches on for "true". SSL_CERT_FILE now reads through truthy, matching
Python's `if ssl_cert_file and ...` check.

Rebuild exception_type around text rules per provider family and one shared
status table. The mapper takes the context, an injected redactor and the
original failure, and returns a PublicError with the message, the real
upstream response and the debug text. Every divergence from the Python
mapper and every known gap is listed in the module header
Match Python on a standalone 429 with an unknown status and on Cohere's
rules for failures without a status. Drop python_repr and the unread
public_failures fixtures
Adds a Rust port of litellm_core_utils/exception_mapping_utils.exception_type
with its provider rule tables (OpenAI-compatible, Cohere, Vertex AI), the
secret redaction patterns from secret_redaction.py, and a Python repr helper
for messages that quote caller values.
The public failure shapes are pinned by golden JSON fixtures under
tests/test_litellm/rust_bridge/fixtures/public_failures, which the Python
side reads too once the bridge is wired to this module. Nothing calls the
port yet.
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.
