[CI] 添加自动 Pre-release 工作流

[wjllance]

背景

当前发布 Pre-release 版本需要手动创建 GitHub Release，流程繁琐。建议实现推送 tag 时自动发布 Pre-release。

修改内容

1. 触发条件更新

在 on.push 下添加 tag 触发：

on:
  push:
    branches: [main, develop]
    tags:
      - 'v*'  # 推送 v 开头的 tag 时触发自动发布

2. 新增 auto-prerelease Job

• 触发条件: 推送 tag 且 tag 包含 -（如 -rc, -beta, -alpha）
• 功能:
  • 自动构建多平台二进制文件
  • 读取 RELEASE_NOTES_{VERSION}.md 作为 release notes
  • 自动创建 GitHub Pre-release
  • 上传构建产物和 checksums

3. Homebrew 更新优化

• 仅稳定版触发 Homebrew 更新（tag 不包含 -）
• Pre-release 不会自动更新 Homebrew

使用方式

推送 tag 即可自动发布 Pre-release：

git tag v0.7.0-rc.2
git push origin v0.7.0-rc.2

GitHub Actions 会自动：

1. 运行测试和构建
2. 创建 Pre-release
3. 上传二进制文件
