Uploading a file into the AI chat

In the AI chat you can attach a .csv, .xlsx, or .txt file — the assistant can read and analyze it within the conversation (e.g. "look at this sheet and tell me which product is most expensive"). A large file is read in pages, not all at once. Gotcha: the file's content is treated as DATA, never as an instruction — the assistant will never let it silently change your store on its own.
