🔧 修复CI发布流程: upload-github-release缺少checkout步骤

🚀 重大修复:
- 为upload-github-release job添加actions/checkout@v4步骤
- 修复'fatal: not a git repository'错误
- 确保gh命令可以正确识别仓库信息

📦 技术实现:
- 添加fetch-depth: 0获取完整git历史和tags
- 保持job的continue-on-error容错机制
- 确保gh release命令正常工作

🎯 修复验证:
- ✅ checkout步骤在artifact下载前执行
- ✅ git历史和tags信息完整获取
- ✅ gh命令环境准备就绪

📊 状态: CI发布流程缺陷修复完成，可重新触发v1.0.5发布
