-##
-# The WebauthnListener class retrieves an OTP after a user successfully WebAuthns with the Gem host.
-# An instance opens a socket using the TCPServer instance given and listens for a request from the Gem host.
-# The request should be a GET request to the root path and contains the OTP code in the form
-# of a query parameter `code`. The listener will return the code which will be used as the OTP for
-# API requests.
-#
-# Types of responses sent by the listener after receiving a request:
-#   - 200 OK: OTP code was successfully retrieved
-#   - 204 No Content: If the request was an OPTIONS request
-#   - 400 Bad Request: If the request did not contain a query parameter `code`
-#   - 404 Not Found: The request was not to the root path
-#   - 405 Method Not Allowed: OTP code was not retrieved because the request was not a GET/OPTIONS request
-#
-# Example usage:
-#
-#   server = TCPServer.new(0)
-#   otp = Gem::WebauthnListener.wait_for_otp_code("https://rubygems.example", server)
-#
