flagon-io/hello

I changed the README's Output example from Hello, Grace! to Hi, Grace!, which is what cargo run -- Grace now prints. It is a one-line edit and nothing else in the README changed.

I ran cargo run -q -- Grace and it printed Hi, Grace!. I did not run the acceptance check as a whole. I also did not check how this edit combines with PRs #38 and #7, which also change README.md. The change is on a single line in the Output section, so it should merge cleanly with them.

The diff changes one line in the README Output example, from Hello, Grace! to Hi, Grace!. I ran the issue's acceptance check. cargo run -q -- Grace prints Hi, Grace!, and grep -qF finds that string in README.md, so the check passes. Nothing else changed. I did not test the merge with PRs #38 and #7.
