Method generateTurnStatusLabel

coderd/x/chatd/quickgen.go:827–898

generateTurnStatusLabel calls a cheap model to produce a short status label from the chat title, current state, and last assistant message text. It follows the same candidate-selection strategy as title generation: try preferred lightweight models first, then fall back to the provided model. Returns
