This PR adds support for mapping the unified `reasoning_effort` field to
Anthropic's `output_config.effort` API parameter, which is the
recommended way to control thinking depth for Claude Opus 4.6 and Sonnet
4.6 models. Previously, the Anthropic provider silently dropped
`reasoning_effort` from requests, while the OpenAI provider already
correctly mapped it to `reasoning: { effort }`. This inconsistency meant
that workflow nodes setting `reasoning_effort: "high"` (the default) had
no effect when routing through Anthropic.
The change adds an `output_config: Option<serde_json::Value>` field to
the `ApiRequest` struct with `skip_serializing_if = "Option::is_none"`
to ensure it's omitted when not set, then populates it in
`build_api_request` by transforming `request.reasoning_effort` into
`{"effort": <value>}` — mirroring the pattern used in the OpenAI
provider. All existing `ApiRequest` constructions in tests are updated
to include `output_config: None`.
The PR also takes the opportunity to refactor the test module by
extracting a `make_base_request()` helper, which reduces boilerplate in
`build_api_request_omits_whitespace_only_system_prompt` and
`make_request_with_format` and makes the two new tests
(`build_api_request_maps_reasoning_effort_to_output_config` and
`build_api_request_omits_output_config_when_no_reasoning_effort`) easy
to read. All existing provider tests continue to pass and no new Clippy
warnings are introduced.
