Satoshi Qazi Muhammed a9d1026736 chore(papi): keep the upstream sources in upstream-src/
The pezkuwi-dev build treats any package with a src/ directory as its
own: it requires our license header on every file and builds it. These
are upstream files that must stay byte-identical to the source embedded
in dist/, so they live in upstream-src/ instead, which neither the build
nor the root tsconfig picks up.
