Vendored from debling/nix-penpot (MIT). Fixes on top: - pnpm fetchers: drop --config.fetch-* flags (UND_ERR_INVALID_ARG on pnpm 11.27) and pin real store hashes (frontend x3, exporter, mcp) - deps-lock.json: add transitive funcool/beicon2 v2.0 so fake-git resolves potok2's pin during the shadow-cljs classpath build - expose frontend pnpm stores via passthru for rehashing - x86_64-linux only; devShell ships afk, jj, git
