JIA-ss ad90bb4645 fix(api): 修复 thinking 块被意外修改导致的 400 错误 ...

问题描述：
使用扩展思考功能时，偶现以下错误：
"thinking or redacted_thinking blocks in the latest assistant message cannot be modified"

根因分析：
当代理服务修改请求体中的某些字段时（如 metadata.user_id、model），
使用 map[string]any 解析整个 JSON 后重新序列化，导致：
1. 字段顺序改变（Go map 序列化按字母排序）
2. 数字格式变化（如 1.0 → 1）
3. Unicode 转义变化

Claude API 对 thinking 块进行字节级验证，任何变化都会触发错误。

修复内容：
1. identity_service.go - RewriteUserID/RewriteUserIDWithMasking
   使用 json.RawMessage 保留其他字段的原始字节

2. gateway_service.go - replaceModelInBody
   使用 json.RawMessage 保留其他字段的原始字节

3. gateway_service.go - normalizeClaudeOAuthRequestBody
   保留 messages 的原始字节，跳过包含 thinking 块的消息修改

4. gateway_service.go - isThinkingBlockSignatureError
   添加 "cannot be modified" 错误检测，触发自动重试

5. antigravity_gateway_service.go - isSignatureRelatedError
   添加 "cannot be modified" 错误检测
