description	Requests that an active BetterForms LLM query stream stop gracefully.

llmQueryStop

llmQueryStop requests that an active /llm/query stream stop.

Expected Options

Key	Type	Description
`options.streamId`	`string`	Stream identifier returned or tracked by the active LLM query flow

{
  "action": "llmQueryStop",
  "options": {
    "streamId": "stream_123"
  }
}

If streamId is missing, BetterForms logs a warning and exits gracefully.
When streamId is present, BetterForms calls the llm/query/stop service.
Failures are handled gracefully so the UI can request stop without needing to trap every stop-state edge case itself.
