Comprehensive server health monitoring for OpenClaw.

## Features

✅ System stats (CPU, RAM, Disk, Uptime)  
✅ Top processes by CPU/RAM  
✅ OpenClaw Gateway status & model config  
✅ Services status (Docker, PostgreSQL, etc.)  
✅ Multiple output formats (standard, JSON, alerts-only)  

## Usage

```bash
# Standard view (default)
./server-health.sh

# JSON output (for automation)
./server-health.sh --json

# Alerts only (warnings/errors)
./server-health.sh --alerts

# Verbose (with temp, network, I/O - coming soon)
./server-health.sh --verbose
```

## Example Output

```
