+-- Add chat_messages.workflow.

+-- (backend/src/routes/chat.ts, projectChat.ts) and reads it back when rendering
+-- chat history (frontend ChatView -> UserMessage, to show which workflow the
+-- message was sent under). The column was referenced in code but never created
+-- by schema.sql or any migration, so every user-message insert failed with
+-- PostgREST PGRST204 ("Could not find the 'workflow' column") and was dropped
+-- silently — user prompts vanished on reload while the assistant reply
+-- persisted. Mirrors the existing content/files jsonb columns.
