DX-982 Adding Chat Namespace to Qstash

[CahidArda]

not sure about whether this section should be updated with llm api

tested with the example project. two logs appear when I call publishJSON or other commands.

One below has the message id returned in the sdk and the message id received in the example project logs

sdk:

{
  messageId: "msg_26hZCxZCuWyyTWPmSVBrNC1RADQsZ6sJoGDscMdG8uFwCUuejU18BXsjePPErcU",
}

project logs:

"sourceMessageId":"msg_26hZCxZCuWyyTWPmSVBrNC1RADQsZ6sJoGDscMdG8uFwCUuejU18BXsjePPErcU"

Not sure if it is related to the sdk or qstash
