feat: create comprehensive local + cloud P2P testing script
🎯 Hybrid Testing Architecture: 🏠 Single Mode (Default): Local machine + 1 Digital Ocean droplet - Local bob daemon + client - Remote alice droplet with server - Real internet P2P communication testing - Cost efficient for development ☁️ Dual Mode (CI): 2 Digital Ocean droplets - Full cloud infrastructure testing - Complete distributed validation - Production environment simulation 📊 Test Flow: 1. Build release binaries (fastn-p2p, request_response) 2. Setup local bob daemon OR create bob droplet 3. Create alice droplet with Echo server 4. Configure identities and protocols 5. Test real P2P communication over internet 6. Validate complete end-to-end flow 7. Automatic cleanup Usage: ./scripts/cli/test-do-p2p.sh # Local + droplet (default) ./scripts/cli/test-do-p2p.sh --dual # Dual droplets (CI) This will definitively prove fastn-p2p daemon MVP works across real internet! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
