Replace map_thinking_to_reasoning_effort() with resolve_reasoning_effort()
that uses a two-tier priority system:
1. Explicit output_config.effort: low/medium/high map 1:1, max → xhigh
2. Fallback: thinking.type + budget_tokens thresholds (<4k → low,
4k-16k → medium, ≥16k → high, adaptive → high)
Both Chat Completions and Responses API paths share the same helper,
ensuring consistent mapping across all OpenAI-compatible endpoints.
* fix(proxy): use max_completion_tokens for o1/o3 series models
When converting Anthropic requests to OpenAI format for o1/o3 series
models (like o1-mini, o3-mini), use max_completion_tokens instead of
max_tokens to avoid unsupported_parameter errors.
Fixes#1448
* fix: revert incorrect o-series max_completion_tokens in Responses API path
Responses API uses max_output_tokens for all models including o-series.
The o-series max_completion_tokens fix should only apply to Chat Completions API.

- Extract shared map_responses_stop_reason and build_anthropic_usage_from_responses into transform_responses.rs as pub(crate)
- Align cache token extraction priority: OpenAI nested details as fallback, direct Anthropic fields as override
- Extract resolve_content_index helper to eliminate 3x copy-paste in streaming_responses.rs
- Add streaming reasoning/thinking event handlers (response.reasoning.delta/done)
- Add explanatory comment to transform_response heuristic detection
- Add openai_responses to api_format doc comment and needs_transform test
- Add explicit no-op match arms for lifecycle events
- Add promptCacheKey to TS ProviderMeta type
- Update toast i18n key to be generic for both OpenAI formats (zh/en/ja)
Support Anthropic ↔ OpenAI Responses API format conversion alongside existing
Chat Completions conversion. The Responses API uses a flat input/output structure
with lifted function_call/function_call_output items and named SSE lifecycle events.
