litellm-router-types mirrors litellm/types/router.py: LitellmParams holds the
model, the credentials, one flattened group per credential family from
auth-types (aws, vertex), the deployment settings a config spells, and every
other key in extra, as Python's extra="allow" keeps it. Config parses it
directly, so config::LiteLlmParams and its untyped additional_fields are gone
and a mistyped provider param is a parse error. fields() and specs() derive
from the families' param specs for hosts that project kwargs and fold module
globals. Spelled<T> is the one untagged shape for a typed value or the text a
config spells, organization takes the list Python's router expands, and the
callback shorthand keeps a value-level one-or-many. No credentials wrapper
group: serde's flatten only consumes keys for struct-shaped children.

* refactor(types): derive Anthropic beta string conversions with Strum
* fix(anthropic): report missing max_tokens as a missing field
* refactor(rust): type Anthropic messages headers and auth after the Python layout
Delete anthropic/messages/headers.rs. Its OAuth handling, credential ladder
and beta merging move to anthropic/common_utils.rs where Python keeps them
(optionally_handle_anthropic_oauth, get_auth_header, _merge_beta_headers),
and the feature beta injection becomes update_headers_with_anthropic_beta on
the messages config, as in Python. The BaseAnthropicMessagesConfig impl is
unchanged apart from the bodies of validate_environment and request_headers
Beta values are now the AnthropicBeta enum and BetaSet, which sort, dedupe
and comma-join by construction. Request params gain typed speed, tools and
context_management through Recognized, so the beta logic matches on enums
instead of string-comparing JSON. OauthToken parses the sk-ant-oat token once
and the chat config shares that detection instead of its own copy
Case-insensitive header helpers move next to has_header in litellm-http.
One deliberate divergence: a Bearer-prefixed OAuth key configured through
api_key or ANTHROPIC_API_KEY is sent with a single Bearer scheme, where
Python would emit "Bearer Bearer"

* done
* fix(rust): repair test compilation and clippy failures
resolve auth before building the outbound request in prepare tests, give the host hook tests their own error type, and drop the disallowed reqwest client and err().expect() from core tests
