feat: P1功能增强 - 3命令+代码高亮+状态行

新增3个命令: - /resume: 恢复已保存的对话(支持list/序号选择) - /export: 导出对话为Markdown文件 - /commit: 创建Git commit(支持AI生成commit message) 代码语法高亮(MarkdownRenderer增强): - 支持Java/JS/TS/Python/Bash/SQL关键字着色 - 字符串字面量黄色、数字紫色、注释灰色斜体 - 注解(@Annotation)亮黄色 - true/false/null 红色 - 新增引用块、有序列表、复选框、链接渲染 - 代码块边框对齐底部状态行(StatusLine): - 模型名、Token用量、费用、API调用次数、工作目录 - 非dumb终端自动启用 - 每次Agent循环后刷新显示 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
