	Long: `Watchdog is a high-performance, cross-platform system monitoring,
automated diagnostics, statistical anomaly detection, SQLite storage engine, and interactive TUI suite.

Key Capabilities:
  - Interactive Terminal Dashboard: Multi-tab real-time CPU/RAM/Disk/Net/Process/Docker TUI.
  - Automated Health Diagnostics: Concurrent heuristic rules with remediation advice.
  - Statistical Anomaly Detection: Real-time Z-score & EWMA anomaly scoring without ML dependencies.
  - Standalone Multi-Format Reports: Rich self-contained HTML (with inline charts), JSON, and CSV.
  - Headless Daemon & Prometheus: Production-ready HTTP REST API and Prometheus metrics exporter.`,
	Example: `  # Launch the interactive real-time terminal UI
  watchdog

  # Run automated health diagnostics and print issues
  watchdog diagnose

  # Generate a standalone HTML health report with charts
  watchdog report -f html -o /tmp/report.html

  # Start the background Prometheus metrics and REST server on port 8443
  watchdog server --port 8443 --token s3cr3t-t0k3n

  # Run with custom configuration and verbose debug logging
  watchdog --config /etc/watchdog.yaml --verbose`,
