Issue #11: Add a Usage section to the README

Under the first paragraph of README.md, add a ## Usage section with a short table of the command-line arguments the program accepts today. Read src/main.rs to find them. Change only README.md.

Make the change and keep it focused on the issue. Commit your work with a clear message. Do not push; that is done for you. Finish with a short summary of what you changed and why. It becomes the description of your pull request, so write it for a reviewer: plain sentences, no headings, no emoji, no checklists, and nothing about whether anything was committed or pushed. Say what you did not verify.

```
/work/repo/src/main.rs

I added a ## Usage section to README.md, directly under the opening paragraph. It has a table of the one command-line argument the program accepts. src/main.rs reads only the first argument, NAME, which is optional. It falls back to the USER environment variable, then to world. The table says this, and that any further arguments are ignored.

The existing example block and the "With no name…" sentence now sit inside the Usage section, after the table. I left them as they were.

I did not run the program. The table comes from reading src/main.rs, not from executing it.
