The getPromptVariables() call in Chat.svelte was missing the $user?.email argument, causing {{USER_EMAIL}} to default to 'Unknown' in the metadata variables sent to the backend. This meant the backend's prompt_variables_template() would replace {{USER_EMAIL}} with 'Unknown' before prompt_template() could substitute the real email from the user object.
