release: v0.4.1 - GitLab支持、迁移优化、Bug修复

✨ 新功能:
- GitLab 平台完整支持（16+7 个 API 方法、前端图标/选择器）
- Release 同步支持手动输入 Token

🐛 Bug 修复:
- 自建平台凭证匹配（BaseURL 优先精确匹配）
- Gitea 迁移 API service 字段类型修复（HTTP 422）
- 构建时不再覆盖已有 config.yaml（数据丢失问题）
- 错误信息显示实际 URL

🔨 改进:
- 源平台开启代理时自动跳过 Gitea 原生迁移，改用本地代理中转
- Push 超时从 30s 提升到 10 分钟
- 设置 http.postBuffer=500MB，push --all 失败自动逐分支推送
- 新增 RunWithProxyTimeout 方法
