feat: Upgrade Packer Integration UI Accessibility and Configuration

[codegen-sh]

🚀 Packer Integration UI Enhancements

This PR significantly improves the Packer-InfoFinder integration by making it fully accessible and configurable via the Chrome extension HTML UI.

✨ What's New

1. Comprehensive Settings UI (Settings Tab)

• ✅ Enable/Disable Toggle - Turn Packer integration on/off easily
• ✅ API Endpoint Configuration - Configure backend server address (default: http://localhost:8765)
• ✅ API Key Support - Optional authentication for secured backends
• ✅ Test Connection - One-click connection testing with visual feedback
• ✅ Real-time Status Indicator - See connection status at a glance
• ✅ Quick Start Guide - Embedded setup instructions in UI

2. New PackerSettingsHandler (src/utils/PackerSettingsHandler.js)

• Manages all settings operations (load/save/test)
• Seamless integration with chrome.storage
• Auto-initializes when Settings tab is clicked
• User-friendly status feedback

3. Enhanced Error Handling (src/ui/PackerIntegrationUI.js)

• Context-aware error messages - Different messages for different failure types:
  • ❌ Connection failures → Backend startup instructions
  • ⏱️ Timeouts → Troubleshooting tips
  • 🚫 System pages → Clear explanation
• Styled Notifications - Beautiful error overlays instead of alerts
• Troubleshooting Tips - Inline guidance for resolving issues

🎯 Benefits

Before	After
No way to configure Packer in UI	Full settings panel in Settings tab
Generic alert() errors	Context-aware styled notifications
Hidden default values	Clear documentation and defaults
No connection testing	One-click test with visual feedback

Summary by cubic

Adds a full Packer-InfoFinder configuration and UI to the Phantom extension, with connection testing, clear status, and exportable results. Improves error handling and integrates a backend bridge for deep JavaScript analysis.

• New Features

  • Settings panel: enable/disable, endpoint, API key, test connection, live status.
  • Backend bridge (PackerBridge.js): health check, analyze, batch, list/get/delete scans.
  • UI integration (PackerIntegrationUI.js): connection indicator, scan button, progress, results view, JSON export.
  • Context-aware errors with troubleshooting and styled notifications.
  • INTEGRATION_GUIDE.md for setup and usage.

• Migration

  • Start the backend in packer-backend.
  • Set endpoint and optional API key in Settings, test connection, then run “Packer深度分析” from the popup.

🎉 Validation & Testing Upgrade Added!

I've just pushed a major upgrade that adds comprehensive testing and validation capabilities to the Packer integration!

✨ What's New

🔬 PackerValidator.js - Complete Validation Framework

A new 500+ line validation module providing:

Input Validation:

• ✅ URL format validation (protocol, hostname, port)
• ✅ Security checks (HTTPS for remote endpoints)
• ✅ API key format validation (length, characters)
• ✅ Real-time validation with visual feedback

Testing Capabilities:

• 🚀 Quick Test (< 3 seconds): Reachability + Auth + Response Time
• 🔬 Comprehensive Test (< 10 seconds): Full endpoint validation + Version detection
• 📊 Beautiful HTML test reports with color-coded results
• ⏱️ Performance metrics and timing data

🎨 UI Enhancements

• Real-time Validation: Input fields turn green (valid) or red (invalid) as you type
• Field-specific Errors: Contextual error messages appear below invalid fields
• New "完整测试" Button: Runs comprehensive validation suite
• Test Reports: Detailed diagnostic information with visual indicators

🛡️ Pre-save Validation

Users cannot save invalid configurations:

• Missing required fields
• Malformed URLs
• Invalid API keys
• Bad port numbers

📊 Test Reports Example

When you click "测试连接" or "完整测试", you now get:

✅ 测试通过 (总耗时: 245ms)

快速测试:
✅ 服务器可访问
✅ 认证成功
✅ 响应时间正常 (245ms)

✅ 分析端点可用
📦 后端版本: 1.0.0

🎯 Benefits

Feature	Before	After
Input Validation	None	Real-time
Error Messages	Generic	Context-aware
Testing	Basic ping	Comprehensive suite
Diagnostics	Minimal	Detailed reports
User Confidence	Low	High

🔧 Technical Details

New Files:

• src/utils/PackerValidator.js - 500+ lines of validation logic

Modified Files:

• src/utils/PackerSettingsHandler.js - Integration with validator
• popup.html - Added comprehensive test button + script reference

Key Methods:

• validateEndpoint() - URL format validation
• validateApiKey() - API key format validation
• quickTest() - Fast connectivity test (< 3s)
• comprehensiveTest() - Full validation suite (< 10s)
• generateTestReport() - HTML report generation

🚀 Usage

Quick Test (Fast, recommended for frequent checks):

1. Configure endpoint/API key
2. Click "🔍 测试连接"
3. Get instant feedback (< 3 seconds)

Comprehensive Test (Thorough validation):

1. Configure endpoint/API key
2. Click "🔬 完整测试"
3. Wait for full diagnostic (< 10 seconds)
4. Review detailed report
