The backtrace-tokens-tree function used a namespaced keyword :temp/id
which clj->js converted to the JS property "temp/id". The sd-token-uuid
function then tried to access .id on the sd-token top-level object,
which was undefined, causing "Cannot read properties of undefined
(reading uuid)".
Fix by using the existing token :id instead of generating a temporary
one, and read it from sd-token.original (matching sd-token-name pattern).
