Add --json output flag to 'runbook status' command

[manthan787]

Description

Add a --json flag to the runbook status command for machine-readable output.

Why

Currently runbook status outputs human-readable text. Adding JSON output would make it easier to:

• Integrate with monitoring tools
• Parse output in scripts
• Build dashboards

What to do

1. Look at src/cli.tsx for the status command implementation
2. Add a --json boolean flag using the existing CLI framework
3. When --json is passed, output structured JSON instead of formatted text
4. Include the same information: service health, recent incidents, etc.

Example output

{
  "timestamp": "2026-02-11T10:00:00Z",
  "services": [
    {"name": "checkout-api", "status": "healthy"},
    {"name": "cart-service", "status": "degraded"}
  ],
  "incidents": []
}

Getting Started

bun install
bun run dev status  # See current output

Good for learning the CLI structure!
