Clean up backup file and migrate GitHub Actions to idris2-pack Docker container

[Copilot]

Cleaned up accidental backup file commit and migrated GitHub Actions workflow to use the official idris2-pack Docker container for reliable Idris2 builds.

Changes

• Removed src/Respo/Effect.idr.bak: Duplicate file that was accidentally committed
• Updated .gitignore: Added *.bak pattern to prevent future backup file commits
• Migrated to Docker container: Replaced manual Idris2 installation with ghcr.io/stefan-hoeck/idris2-pack:latest Docker container, which is the standard approach used by major Idris2 projects (idris2-dom, idris2-lsp, idris2-pack)

Benefits

• Faster builds: No more 10-15 minute Idris2 compilation from source
• More reliable: Pre-built environment with all dependencies included
• Simpler workflow: Reduced workflow complexity by 33 lines of code
• Best practices: Following the same approach used by the Idris2 community

The workflow now uses the official idris2-pack container which includes Idris2 with proper JavaScript codegen support pre-configured.

@copilot 详细分析 actions 构建的问题, 搜索其他 idris2 编译 js 的项目, 然后提供一个修复方案, 直到最终修复(max 20 steps)

我已完成详细分析并提供了修复方案:

问题分析

通过研究类似的Idris2项目(idris2-dom, idris2-lsp, idris2-pack等),发现主要问题:

1. 手动安装Idris2过于复杂

   • 从源码编译需要10-15分钟
   • 缓存路径与安装PREFIX不匹配
   • JavaScript代码生成器支持配置容易出错

2. 环境变量配置错误

   • 之前设置IDRIS2_PREFIX=/usr/local/idris2-0.8.0,但实际安装在/usr/local

解决方案

已切换到使用**ghcr.io/stefan-hoeck/idris2-pack:latest Docker容器**:

✅ 预装Idris2及所有依赖
✅ 被主流Idris2项目广泛使用(idris2-dom, idris2-lsp, idris2-pack等)
✅ 构建速度更快、更可靠

实现的改进

1. 移除了复杂的手动安装和缓存逻辑(减少33行代码)
2. 简化构建步骤
3. 删除了错误的IDRIS2_PREFIX环境变量设置
