Fix API inconsistencies in README

- Change socket.close() from throwing to async (await socket.close())
- Fix event stream property name from 'events' to 'event'
- Update socket option getter to use subscript syntax (socket[.keepAlive])
- Remove unsupported scopeID parameter from IPv6SocketAddress example
