Submit fails with “No files you submitted have changed” even on first submission #1197
Description
Hey team! I’m new to Exercism and trying out the Go track, but I’ve hit a snag with the CLI.
I tried to submit my very first hello_world solution, and got this error:
Error: No files you submitted have changed since your last submission
For more detail, I tried exercism submit -v and got the dump below.

I haven’t made any prior submissions, so it feels like the server or CLI thinks this is a duplicate.
Thanks for any pointers! Let me know if I missed something obvious. 😊
