Describe the bug

I have seen a failure like this a couple of times now on GHC's CI while fetching:

error: uri https://github.com/edolstra/flake-compat/archive/ff81ac966bb2cae68946d5ed5fc4994f96d0ffec.tar.gz changed final destination from https://github.com/edolstra/flake-compat/archive/ff81ac966bb2cae68946d5ed5fc4994f96d0ffec.tar.gz to https://codeload.github.com/edolstra/flake-compat/tar.gz/ff81ac966bb2cae68946d5ed5fc4994f96d0ffec during transfer

See for instance: https://gitlab.haskell.org/ghc/head.hackage/-/jobs/2311058

I'm not sure if this is a bug in Lix proper or something wrong with the CI environment in which it is running.

We are running Lix-2.93.3 using the official Docker image.

Steps To Reproduce

As far as I can tell the error is not easily reproducible and intermittent.
We have only seen it twice.

Expected behavior

We shouldn't error if GitHub decides that it wants to redirect us quite oddly mid transfer like this.

Lix version

2.93.3 using the official docker image

this is github redirecting a download of a file to two different urls depending on ... something. today we reject such redirects because they're an easy cause of undetectable corruption, but perhaps the error should be downgraded to a warning
