Use adaptive thinking for Claude requests and rewrite passthrough bodies that still contain the legacy enabled type.

Co-Authored-By: Codex <noreply@anthropic.com>

gpt-5.4 returns `arguments` as a JSON object for some tools (e.g.
apply_patch, tool_search), but ResponsesOutput.Arguments was typed as
string, causing json.Unmarshal to fail on every such SSE event.

The failure silently dropped all output_item events and the
response.completed event from the forwarded stream, so:
- the client never received tool call content
- usage/token counts could not be extracted (billed as 0)
- client reported "stream closed before response.completed"

Fix: change Arguments to json.RawMessage and add GetArguments() which
normalises both forms to a plain string (unescapes JSON strings,
returns raw bytes for objects).

DoApiRequest previously called io.ReadAll on every request body to apply
passthrough model mapping, even when the feature was disabled. This
caused unnecessary memory pressure for large request bodies (long
conversations, multipart image uploads).

Split the guard logic into needsPassthroughModelMapping() so that
ReadAll is only called when all conditions are met (feature enabled +
passthrough mode + model mapped). Non-passthrough requests now pass
the original io.Reader directly to http.NewRequest without buffering.

Rewrite tests to verify combined guard + modify behavior.

This reverts commit ff14caed7c.

   而非写入 fallback 值 1，避免覆盖全局正确的 0.1
2. Claude 响应使用 GetCacheCreationTotalTokens() 替代直接读
   CacheCreationInputTokens，兼容新版本子对象格式
3. 新增 GetAudioRatioV2/GetAudioCompletionRatioV2 带 bool 返回
