Add connection retry with timeout to AppProvider so apps self-heal when the PostMessage handshake races on first load in ChatGPT/Claude. Add periodic sandbox-proxy-ready retries to handle srcdoc/React ref timing. Suppress noisy "Server not initialized" transport errors during parallel connections. Add troubleshooting guide to docs site, READMEs, CLI output, and agent skill.
