Incompatibilities for unusable distributions are not combined

e.g.

❯ uv pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
  × No solution found when resolving dependencies:
  ╰─▶ Because only the following versions of torch are available:

      and torch==0.1 is unusable because no wheels are available with a matching Python ABI, we can conclude that
      torch<0.1.6.post17 cannot be used.
      And because torch==0.1.6.post17 is unusable because no wheels are available with a matching Python ABI and
      torch==0.1.6.post20 is unusable because no wheels are available with a matching Python ABI, we can conclude that
      torch<0.1.6.post22 cannot be used.
      And because torch==0.1.6.post22 is unusable because no wheels are available with a matching Python ABI and
      torch==0.1.7.post2 is unusable because no wheels are available with a matching Python ABI, we can conclude that

      And because torch==0.1.8.post1 is unusable because no wheels are available with a matching Python ABI and
      torch==0.1.9.post1 is unusable because no wheels are available with a matching Python ABI, we can conclude that

      And because torch==0.1.9.post2 is unusable because no wheels are available with a matching Python ABI and
      torch==0.1.10.post1 is unusable because no wheels are available with a matching Python ABI, we can conclude that

      And because torch==0.1.11.post4 is unusable because no wheels are available with a matching Python ABI and
      torch==0.1.11.post5 is unusable because no wheels are available with a matching Python ABI, we can conclude that

      And because torch==0.2.0.post1 is unusable because no wheels are available with a matching Python ABI and
      torch==0.2.0.post2 is unusable because no wheels are available with a matching Python ABI, we can conclude that
      torch<0.2.0.post3 cannot be used.
      And because torch==0.2.0.post3 is unusable because no wheels are available with a matching Python ABI and
      torch==0.3.0 is unusable because no wheels are available with a matching Python ABI, we can conclude that
      torch<0.3.0.post2 cannot be used.
      And because torch==0.3.0.post2 is unusable because no wheels are available with a matching Python ABI and

      And because torch==0.3.0.post4 is unusable because no wheels are available with a matching Python ABI and
      torch==0.3.1 is unusable because no wheels are available with a matching Python ABI, we can conclude that torch<0.4.0
      cannot be used.
      And because torch==0.4.0 is unusable because no wheels are available with a matching Python ABI and torch==0.4.1
      is unusable because no wheels are available with a matching Python ABI, we can conclude that torch<1.11.0 cannot
      be used.
      And because torch==1.11.0 is unusable because no wheels are available with a matching Python ABI and torch==1.12.0
      is unusable because no wheels are available with a matching Python ABI, we can conclude that torch<1.12.1 cannot
      be used.
      And because torch==1.12.1 is unusable because no wheels are available with a matching Python ABI and torch==1.13.0
      is unusable because no wheels are available with a matching Python ABI, we can conclude that torch<1.13.1 cannot
      be used.
      And because torch==1.13.1 is unusable because no wheels are available with a matching Python ABI and torch==2.0.0 is
      unusable because no wheels are available with a matching Python ABI, we can conclude that torch<2.0.1 cannot be used.
      And because torch==2.0.1 is unusable because no wheels are available with a matching Python ABI and you require
      torch, we can conclude that the requirements are unsatisfiable.

We should combine all of these incompatibilities into a single range.
