Generate Prompt

Generate improved scorer prompt using Autotune (CLHF).

This endpoint:

1. Fetches all feedback items from the active queue with ClickHouse context
2. Assembles the current metric system prompt
3. Constructs AutotuneInput with annotated examples
4. Queues a background job to the runners service
5. Returns task_id for polling

The API prepares all data internally - no request body needed.

Validation:

• Scorer exists and user has access
• Active queue exists in 'pending' state
• Queue has at least one feedback item

Response:

• 202 Accepted with task_id for polling

Errors:

• 404 - Scorer not found or no active pending queue exists
• 409 - Queue is already locked (generating or reviewing)
• 422 - Scorer missing required configuration or queue has no feedback items
