yet another insane crutch made in 2 hours for local jsr instances, yayy. this time - to populate local instance with upstream packages. something that should honestly been done in jsr itself, similarly to how verdaccio handles it (by simply proxying shit), but whatever lol. sometimes i feel like i made more useful tooling around jsr than jsr devs themselves tbh if only deno supported per-scope `JSR_URL`-s... i should open an issue about that actually
