feat: add auto-start on boot and restructure README (v1.5.0)

- setup.mjs: install launchd plist (macOS) or systemd user service (Linux) after proxy starts; logs to ~/.openclaw/logs/proxy.log
- Add uninstall.mjs to stop and remove the auto-start entry
- README: Quick Start (Node.js) first, Security section, Docker moved to Server/Advanced
- Bump version to 1.5.0
