* feat(rust): one typed decline from core up to each host
Rust core says it cannot serve a request with one Decline that travels
unchanged through llms and inference up to the host. The Python bridge
raises RustBridgeDeclined for it in route_failure before the public
exception mapping, so dispatch falls back to legacy Python instead of
failing the call, and the gateway answers 501. Every route collapses
errors after the send with Error::after_send, which keeps a provider
answer and a response fault as they are and nests anything else as the
source of an invalid response, so a billed call can never read as a
decline. Response-side cases that used to decline are now
ErrorDetail::Unhandled response faults.
The rust-error skill documents declined() as the first question both
boundaries ask, and the Python suites pin that a native decline reaches
the dispatcher before any provider IO.

* test(rust-bridge): pin Messages and Responses callback contracts on the native path
Each test runs the native route and asserts what the Python path does today, so a
known gap is a strict xfail that names its reason and the exception it fails with
Messages and Responses share one Surface and hook recorder in support/callbacks.py,
and each surface folder lists its own expected counts and gaps.
Body-level hooks from the function body (pre-request hook, websearch short-circuit,
Messages interceptors, planned and legacy agentic loops, streaming deployment hook)
are xfail until native runs them

* test(rust-bridge): give every route folder the same one-concern-per-file layout
Route data, the route Surface and the server fixture move into each route folder, and support/ keeps only
route-neutral helpers. test_inference.py splits into chat_completions/ and responses/, ocr/test_requests.py
splits into requests, failures and settings, and Messages and Responses get streaming and body hook files.
Messages request tests that duplicate inference-messages request.rs are removed, and drop_params read
from litellm.drop_params is now covered
