<pre>
    In workflows like https://github.com/llvm/llvm-project/actions/runs/17234316420/job/48895489095, `sccache` is failing build actions.

It seems like the server is dying and then the clients are not failing gracefully and falling back to local compilation. I can reproduce this locally by killing the server. Not sure why the server is dying. I think there are two things we need to do here:
1. [ ] Figure out why the server is dying. I'm hoping we can get some info by setting `SCCACHE_LOG=info` and dumping the log file into the artifacts.
2. [ ] Make `sccache` fail gracefully when it cannot connect to the server.
