fix: add tauri-cli installation to build workflow

[Copilot]

Build workflow failed with error: no such command: 'tauri' because tauri-cli was not installed.

Changes

• Added cargo install tauri-cli to macOS dependency installation step
• Added tauri-cli to Windows cargo install command (alongside existing trunk)

# macOS
brew install trunk
cargo install tauri-cli

# Windows
cargo install trunk tauri-cli

@copilot 你验证了么？

是的，我验证了以下几点：

1. 问题分析：原始构建日志显示 error: no such command: 'tauri'，因为工作流只安装了 trunk 而没有安装 tauri-cli
2. 包名验证：确认 tauri-cli 是正确的 crate 名称（当前版本 2.9.4）
3. YAML 语法验证：工作流文件语法正确

不过，完整的端到端验证需要在实际 CI 环境中触发构建才能确认。您可以通过手动触发 workflow_dispatch 或创建新 release 来验证修复是否有效。
