fix(gateway): 兼容 Cursor /v1/chat/completions 的 Responses API body
...
Cursor 云端 (User-Agent: Go-http-client/2.0) 发往 /v1/chat/completions 的
body 使用 Responses API 格式:
{"model":"gpt-5.4","input":[{"role":"system","content":"..."}],"stream":true}
原代码用 ChatCompletionsRequest 反序列化,该结构体没有 Input 字段,
Cursor 的 input 数组被静默丢弃,ChatCompletionsToResponses 转换后产出
input: null,Codex 上游以 "Invalid type for 'input': expected a string,
but got an object" 拒绝请求(上游 typeof null === 'object')。
修复:在 ForwardAsChatCompletions 里用 gjson 检测 body shape,当 input
存在且 messages 缺失时,跳过 Chat→Responses 转换,用 sjson 仅改写 model
字段后原样透传 body。billing 所需的 ServiceTier 和 Reasoning.Effort 通过
gjson 从 raw body 提取,下游 codex OAuth transform 路径保持不变。
测试:新增 openai_cursor_warmup_pipeline_test.go,覆盖 5 个 shape 检测
用例(正向/标准请求不误伤/两字段共存/空 body/JSON 回读)。

fix: 非流式路径在上游终态事件output为空时从delta事件重建响应内容
...
上游API近期更新后，response.completed终态SSE事件的output字段可能为空，
实际内容仅通过response.output_text.delta等增量事件下发。流式路径不受影响，
但chat_completions非流式路径和responses OAuth非流式路径只依赖终态事件的
output，导致返回空响应。
新增BufferedResponseAccumulator累积器，在SSE扫描过程中收集delta事件内容
（文本、function_call、reasoning），当终态output为空时补充重建。
同时修复handleChatBufferedStreamingResponse遗漏response.done事件类型的问题。

refactor: remove resolveOpenAIUpstreamModel, use normalizeCodexModel directly
...
Eliminates unnecessary indirection layer. The wrapper function only
called normalizeCodexModel with a special case for "gpt 5.3 codex spark"
(space-separated variant) that is no longer needed.
All call sites now use normalizeCodexModel directly.

feat(service): record upstream model across all gateway paths
...
Propagate UpstreamModel through ForwardResult and OpenAIForwardResult in Anthropic direct, API-key passthrough, Bedrock, and OpenAI gateway flows. Extract optionalNonEqualStringPtr and optionalTrimmedStringPtr into usage_log_helpers.go. Store upstream_model only when it differs from the requested model.
Also introduces anthropicPassthroughForwardInput struct to reduce parameter count.

refactor: 重构 Chat Completions 端点，采用类型安全的 Responses API 转换
...
将 /v1/chat/completions 端点从 ResponseWriter 劫持模式重构为独立的
类型安全转换路径，与 Anthropic Messages 端点架构对齐：
- 在 apicompat 包新增 Chat Completions 完整类型定义和双向转换器
- 新增 ForwardAsChatCompletions service 方法，走 Responses API 上游
- Handler 改为独立的账号选择/failover 循环，不再劫持 Responses handler
- 提取 handleCompatErrorResponse 为 Chat Completions 和 Messages 共用
- 删除旧的 forwardChatCompletions 直传路径及相关死代码
