feat(rust): shape Anthropic Messages requests natively (#42982)
* test(rust): encode anthropic response serialization shape as rstest cases

* feat(rust): shape Anthropic Messages requests natively

The Rust Messages route only relayed the body. It now runs the request shaping
the Python handler does for the direct Anthropic provider: history sanitizers
(empty blocks, tool ids, replayed web search results, provider_specific_fields,
encrypted reasoning, advisor blocks), reasoning_effort and adaptive/legacy
thinking translation against the model's capability flags, the sampling and
speed gates under drop_params, the metadata allowlist, additional_drop_params,
reasoning auto summary, OAuth and ANTHROPIC_AUTH_TOKEN credentials,
provider_specific_header merging and anthropic-beta injection. Capability flags
and LiteLLM settings reach Rust through route_host.shaping(). A request the
route rejects before the call now maps to BadRequestError instead of
APIConnectionError

* test(rust): port Anthropic Messages shaping tests and pin comment contracts as cases

Every Python unit test that exercises the ported shaping for the direct
Anthropic provider now has a named rstest counterpart, and every comment that
stated a behavior contract is deleted in favor of a case that pins it. Measured
with cargo-mutants over the touched files, all viable mutants are caught

Porting the tests surfaced parity gaps, fixed here to match Python: every
casing of a forwarded anthropic-beta header is merged, replayed web search
results are rewritten from their own block (an empty result keeps its slot and
a server_tool_use with a non-string query stays), an empty output_config.effort
falls back to medium, speed and reasoning effort errors quote values the way
Python does, additional_drop_params apply after metadata validation and the
auto summary and never touch model or messages, and a non-string
metadata.user_id is rejected before the call

* fix(rust): resolve Messages credentials through the secret source and scope headers by resolved provider

The native Messages route read ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN and the
base URL straight from the process environment, so a key or base held in a
configured secret manager was never found. Each provider config now declares
its secret names and the route resolves them through the same SecretSource the
OCR route uses, with the Python bridge passing in litellm's configured manager

provider_specific_header entries were scoped by the explicit
custom_llm_provider only, falling back to anthropic, so an azure_ai/ model
lost its azure_ai scoped headers. Scoping now happens in the route after the
provider is resolved from the model, as Python's handler does

The Azure config now adds the same anthropic-beta feature headers Python's
Azure route adds, and the metadata allowlist, reasoning auto summary and
history sanitizers move from the core route into the llms crate, mirroring
their home in Python's messages handler

* test(rust): escape the dot in the metadata.user_id match pattern

* refactor(rust-bridge): project Messages capabilities without mutable dicts

The capability flags and effort tiers were built as dict comprehensions,
which the type-discipline gate counts as mutable construction, and the
asdict call carried a mutable-ok suppression that suppressed nothing. The
flags are now passed one by one and the effort tiers are a frozen dataclass,
which asdict projects to the same map the native side reads

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
