feat: v0.10.0 —— 表格可编辑控件，单行代码块的语言按钮挪位

代码块
- 只有一行代码时，框太矮，语言下拉自动挪到复制按钮左边同一行

表格
- 检测 Markdown 表格（表头 + |---| 分隔行 + 连续 | 行），在编辑模式下用
  QTableWidget 覆盖渲染：圆角边框、网格线、表头加粗、按 :---: 保留对齐
- 双击单元格直接编辑，改完立刻回写成 Markdown 表格
- 右键菜单：插入行 / 删除行 / 插入列 / 删除列，改完同步回文本
- 新增行/列会沿用原有对齐；表格增删行后自动修正后面表格的行号偏移
- 源代码模式下表格退回原始 Markdown 文本（控件隐藏）
- 主题切换时重建控件以套用新配色

其它
- 欢迎文档与演示文档各加一张示例表格
- 新增 4 条中英文翻译（插入行/删除行/插入列/删除列）
- 版本 0.10.0
