cannot create packages from purls

[JonoYang]

The packagedb has a constraint where all Packages need to have unique download_urls and the purls provided by the federatedcode repos do not contain them

Some actions that we can take to address this:

• Store all qualifiers for purls such that we could reconstruct a download url
• Set download_url qualifier
• Update purl2url

Hi @JonoYang ! I’m Vishal (PixelCraftLab). I’m interested in contributing and preparing for GSoC 2026.
Could you please assign this issue to me? Also, a bit of guidance on whether to focus on storing all PURL qualifiers or updating purl2url for setting download_url would be helpful.
Thanks!

Hi @JonoYang , I was going through the purldb codebase and came across this issue...felt like a good fit and hence tried to solve it. I've raised a PR #860 with a proposed fix, can you please review it?
