feat: deploy pipeline to mcp.vultisig.com

[RaghavSood]

Summary

• Adds GitHub Actions deploy workflow that deploys on every push to main
• Adds scripts/deploy.sh adapted from vultisig/verifier

Server Setup (already done)

• Server: 129.212.217.161 (Debian 13, Go 1.25.5)
• DNS: mcp.vultisig.com
• nginx: reverse proxy on port 443 → localhost:8080, with Let's Encrypt SSL
• systemd: mcp.service running /usr/local/bin/mcp-server -http :8080
• env: /opt/mcp/.env with ETH_RPC_URL and COINGECKO_API_KEY

GitHub Secrets (already set)

• SSH_KEY — deploy key for server access
• SSH_SERVER — 129.212.217.161
• SSH_USER — root
• SSH_PATH — /opt/mcp

Deploy Flow

1. Push to main triggers workflow
2. Tests run (go vet + go test)
3. On success: rsync → go build on server → systemctl restart mcp

Verification

Server is already live and responding:

$ curl -s -X POST https://mcp.vultisig.com/mcp -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{...}}'
{"jsonrpc":"2.0","id":1,"result":{"serverInfo":{"name":"vultisig-mcp","version":"0.1.0"}}}

Test plan

• Server is running and accessible at https://mcp.vultisig.com
• SSL certificate is valid (Let's Encrypt, auto-renewal enabled)
• GitHub secrets configured
• CI deploy workflow runs on merge
