fix(opensource): 项目墙卡片左对齐与 bio 间隙兜底（视觉终审二轮）

Finding 1（P1）项目墙卡片内容被居中：
- 根因是全局 `.tap { display:inline-flex; align-items:center; justify-content:center }`
  沿列向 flex 的交叉轴生效，`.repo`（scoped）只赢下 display 没接管 align-items，
  于是标题与「● 语言 ★ n」行落在卡中部、卡片间左缘参差
- `.repo` 显式 align-items: stretch + text-align: left；实测四张卡的
  .repo-name 与 .repo-meta 左缘全部 313px（= 卡左 296 + 内距 16 + 边框 1）

Finding 2（P2）bio 破折号间隙修在数据不在模板：
- 原靠 opensource.yaml 串前导空格产生间隙，后台清空走兜底串时缺陷回归
- 模板改为 `{a}{' '}{blurbAfter.trim()}`：间隙由模板保证，数据怎么改都不会贴链接

验证: 构建 51 页 exit 0；content-lint 0/0/0；spec_verify 七项 exit=0（新指纹
      62086ce4cccd）；check 收敛；DOM 实测对齐与间隙均符合预期
