Fix socket namespace readiness and add AsyncBot API

- force explicit '/' namespace connect with readiness checks
  - add guarded emits with disconnect reason diagnostics
  - add configurable socket transports (e.g. websocket-only)
  - introduce AsyncBot based on socketio.AsyncClient
  - export AsyncBot and document async quick-start/troubleshooting
  - bump package version for release
