The options for the WebSocket transport.

• :name - The name of the transport process, respecting the GenServer "Name Registration" section.
• :client - The client to send the messages to, respecting the GenServer "Name Registration" section.
• :server - The server configuration.
• :headers - The headers to send with the WebSocket upgrade request.
• :transport_opts - A keyword list or map of options passed to HTTP.WebSocket.new/3, including the library's supported string map keys. The transport always overrides owner and headers, including string keys. Only browser mode with legacy delivery is supported; ACK delivery and proxy mode are rejected. Incoming text messages are forwarded to the client; binary messages are ignored. TLS verification uses the library defaults unless explicitly configured through these options.
