chore:1.10.5

* feat: langfuse tracing 增加 thinking 参数记录

在 recordLLMObservation 中添加 thinking 配置（type/budgetTokens），
所有 provider（claude/gemini/openai）及 tokenEstimation、sideQuery
调用处同步传递 thinking 信息，便于 Langfuse 面板观察 thinking 使用情况。

* fix: langfuse tracing 兼容 budget_tokens snake_case 格式

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix: 统一传递完整 thinking 配置而非仅 thinkingType

Langfuse 追踪直接传递整个 thinking 对象（含 type 和 budget_tokens），
Analytics 日志同步补充 thinkingBudgetTokens 字段，logAPIQuery 改为
接收 ThinkingConfig 类型参数。

* feat: 省略旧消息的代码 diff 展示，仅保留最新消息的完整 diff

* fix: Edit 工具增加 Tab/空格规范化匹配，修复中文和缩进文件编辑失败

Read 工具输出将 Tab 渲染为空格，用户复制后 Edit 工具无法匹配。
在 findActualString 中增加 Tab→空格规范化回退匹配，并精确映射回原始文件位置。
