feat: add PM2 configuration and deployment setup for remote server

- Add Makefile with convenient PM2 commands for development and production
- Add ecosystem.config.js with production/staging/dev environment configurations
- Add comprehensive PM2-GUIDE.md documentation for deployment
- Update package.json with PM2-specific npm scripts
- Fix Chrome extension URL handling to omit standard ports (443/80)
- Hide embedding model and semantic engine sections in popup UI

+# PM2 Deployment Guide for MCP Remote Server
+
+This guide explains how to run the MCP Remote Server using PM2 for production deployment.
+
+## Prerequisites
+
+1. **Node.js** (v18 or higher)
+2. **PM2** (Process Manager)
+
+## Quick Start
+
+### 1. Install PM2 (if not already installed)
+
+```bash
+# Install PM2 globally
+npm install -g pm2
+
+# Or using the Makefile
+make pm2-setup
+```
+
+### 2. Start the Server
+
+```bash
+# Using Makefile (recommended)
+make pm2-start
+
+# Or using npm scripts
+npm run pm2:start
+
+# Or directly with PM2
+pm2 start ecosystem.config.js
+```
+
+### 3. Monitor the Server
+
+```bash
+# Check status
+make pm2-status
+# or
+pm2 status
+
+# View logs
+make pm2-logs
+# or
+pm2 logs mcp-remote-server
+
+# Monitor in real-time
+pm2 monit
+```
+
+## Available Commands
+
+### Makefile Commands
+
+```bash
+make pm2-start     # Start server with PM2
+make pm2-stop      # Stop server
+make pm2-restart   # Restart server
+make pm2-status    # Show status
+make pm2-logs      # Show logs
+make pm2-delete    # Delete PM2 process
+```
+
+### NPM Scripts
+
+```bash
+npm run pm2:start    # Start with PM2
+npm run pm2:stop     # Stop server
+npm run pm2:restart  # Restart server
+npm run pm2:reload   # Reload (zero-downtime)
+npm run pm2:status   # Show status
+npm run pm2:logs     # Show logs
+npm run pm2:monit    # Open monitoring dashboard
+```
+
+## Environment Configuration
+
+The server supports multiple environments configured in `ecosystem.config.js`:
+
+### Production
+
+```bash
+pm2 start ecosystem.config.js --env production
+```
+
+- PORT: 3040
+- HOST: 0.0.0.0
+- DOMAIN: https://mcp-browser.qubecare.ai
+
+### Development
+
+```bash
+pm2 start ecosystem.config.js --env development
+```
+
+- PORT: 3040
+- HOST: 0.0.0.0
+- DOMAIN: http://localhost:3040
+
+### Staging
+
+```bash
+pm2 start ecosystem.config.js --env staging
+```
+
+- PORT: 3040
+- HOST: 0.0.0.0
+- DOMAIN: https://staging-mcp-browser.qubecare.ai
+
+## Logs
+
+Logs are stored in the `logs/` directory:
+
+- `logs/combined.log` - All logs
+- `logs/out.log` - Standard output
+- `logs/error.log` - Error logs
+
+## Auto-restart on System Boot
+
+To automatically start the server on system boot:
+
+```bash
+# Save current PM2 processes
+pm2 save
+
+# Generate startup script
+pm2 startup
+
+# Follow the instructions provided by PM2
+```
+
+## Monitoring and Management
+
+### Real-time Monitoring
+
+```bash
+pm2 monit
+```
+
+### Process Information
+
+```bash
+pm2 show mcp-remote-server
+```
+
+### Resource Usage
+
+```bash
+pm2 list
+```
+
+## Troubleshooting
+
+### Server Won't Start
+
+1. Check if port 3040 is available
+2. Verify the build was successful: `npm run build`
+3. Check logs: `pm2 logs mcp-remote-server`
+
+### High Memory Usage
+
+The server is configured to restart if memory usage exceeds 1GB. You can adjust this in `ecosystem.config.js`:
+
+```javascript
+max_memory_restart: '1G'; // Change to desired limit
+```
+
+### Connection Issues
+
+1. Verify the server is running: `make pm2-status`
+2. Check health endpoint: `curl http://localhost:3040/health`
+3. Review error logs: `pm2 logs mcp-remote-server --err`
+
+## Production Deployment
+
+For production deployment, ensure:
+
+1. **Environment Variables**: Update `.env` file or ecosystem config
+2. **Domain Configuration**: Set correct DOMAIN in ecosystem.config.js
+3. **SSL/TLS**: Configure reverse proxy (nginx/apache) for HTTPS
+4. **Firewall**: Open port 3040 or configure reverse proxy
+5. **Monitoring**: Set up external monitoring for the health endpoint
+
+## Security Considerations
+
+1. **Firewall**: Restrict access to port 3040
+2. **Reverse Proxy**: Use nginx/apache for SSL termination
+3. **Environment Variables**: Keep sensitive data in environment variables
+4. **Updates**: Regularly update dependencies
+
+## Example Production Setup
+
+```bash
+# 1. Clone and setup
+git clone <repository>
+cd app/remote-server
+npm install
+
+# 2. Configure environment
+cp .env.example .env
+# Edit .env with production values
+
+# 3. Start with PM2
+make pm2-start
+
+# 4. Setup auto-restart
+pm2 save
+pm2 startup
+
+# 5. Monitor
+make pm2-status
+```
