* fix: support OpenAI SDK 3.x while retaining 2.x compatibility
* fix: preserve HTTPX compatibility across OpenAI SDK versions
* refactor: trim OpenAI SDK compatibility patch
* refactor: simplify SDK client defaults
* test: cover SDK compatibility across provider routes
* fix: use shared names for SDK transport helpers
* fix: address SDK compatibility review feedback
* test(openai): send requests through the SDK API factory clients
* fix(exceptions): keep the provider response on PaymentRequiredError under httpx 2
* ci(base-sdk): count httpx2 as base-only when a base dependency brings it in
OpenAI SDK 3 depends on httpx2, so the litellm-core install at highest resolution pulls it in through openai. The base-only check now resolves the declared base dependency closure of litellm and litellm-core and accepts extras-only modules owned by a distribution inside that closure
* test: cover OpenAI SDK 3 client paths end to end and read SDK HTTP headers case-insensitively
* test: read C02 spend rows once, wait out the worker healthcheck on respawn, and resolve module owners on Python 3.10

`lite up` treats a token record whose key the keychain would not hand over as no
login at all, and that clause had no test: every existing freshness test passed a
record carrying a real key, so deleting the clause left the whole suite green
The base install smoke check now also asserts keyring is absent, which is what
makes the lazy import in cli_keyring meaningful. keyring ships in the cli extra
only, so a plain `pip install litellm` must not be able to reach it
* fix(deps): ship boto3 with the base SDK so bedrock works out of the box
* keep boto3 listed in the proxy extra as well
* scrub ambient AWS env vars in the base SDK bedrock smoke check
`import litellm` reaches litellm/integrations/otel/model/config.py via
litellm_core_utils/litellm_logging.py, so pydantic-settings is needed at import
time. It was declared only in the `proxy` extra, which left a plain
`pip install litellm` unimportable on every platform.
Adds tests/base_sdk_tests/check_base_sdk_install.py and a base_sdk_install
CircleCI job that builds the wheel, installs it into a clean venv with no extras,
and smoke-checks the import, a mock completion, a mock embedding, the bundled
pricing metadata and the token counter. The check is stdlib-only on purpose;
installing pytest into that venv would add packaging, pluggy and iniconfig and
could mask the class of undeclared dependency it exists to catch.
Previously the Windows job was the only one installing without extras, so this
class of break was caught by accident rather than by design.
