Add AGENTS.md for GitHub Copilot CLI context on Mac

[Copilot]

Creates comprehensive AI assistant documentation for the HBuilderX uni-app testing plugin, targeting GitHub Copilot CLI usage on Mac terminals.

Content Structure

• Project architecture: Complete source tree with module responsibilities (extension.js, HBuilderXCli.js, TestCaseRun.js, etc.)
• CLI command reference: All supported platforms (web-chrome/safari/firefox, mp-weixin, app-android/ios-simulator/harmony) with Mac-specific examples
• Development patterns: HBuilderX API usage, command registration, async handling, device management
• Testing guide: Jest code snippets, multi-platform test structures, platform-specific constraints
• AI integration examples: Concrete scenarios for adding test assertions, CLI parameters, error messages

Key Sections

# Mac terminal CLI examples
cli uniapp.test web-safari --project ~/Projects/my-uniapp
cli uniapp.test app-ios-simulator --project ~/Projects/my-uniapp
cli uniapp.test app-android --project ~/Projects/my-uniapp --testcaseFile pages/login/login.test.js

// HBuilderX command registration pattern
let cli_command = hx.commands.registerCliCommand('uniapp.test platform', async (params) => {
    await RunTestForHBuilderXCli_main(params, 'platform');
});

File provides context for AI tools to generate code consistent with HBuilderX plugin architecture, Jest testing framework, and multi-platform automation (Puppeteer, ADBKit, node-simctl).
