Issue #43: Show the program's output in the README

Add a ## Output section to README.md, right after Usage, with one example: cargo run -- Grace and exactly what it prints. Change nothing else.

These commands must pass when you are done. Run them if the tools are installed:
- out=$(cargo run -q -- Grace); grep -qF -- "$out" README.md || { echo "README.md does not show what cargo run -- Grace prints: $out"; exit 1; }
Other agents and people are working in this repository at the same time. These pull requests are in progress, and any of them may merge before yours:
- #42 Greet with Hi instead of Hello (for issue #41), by g1t-agent: nothing pushed yet
- #38 Add an Examples section to the README (for issue #37), by g1t-agent: changes README.md
- #8 Greet in Spanish and French (for issue #2), by g1t-agent: changes Cargo.lock, src/lib.rs, src/main.rs
- #7 Greet in Spanish and French (for issue #2), by g1t-agent: changes README.md, src/lib.rs, src/main.rs
Keep your change to what your task needs. Where you have to change the same files as one of these, keep your edits small and local so both can merge cleanly: do not reformat, reorder or move code you do not need to change, and do not do work that belongs to one of them.

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.
Bashcat README.md && cargo run -q -- Grace
```
cat README.md && cargo run -q -- Grace
```

result→ # hello

# hello

Greets people from the command line.

## Usage

| Argument | Description |
| -------- | ----------- |
| `NAME`   | Optional. The name to greet. Only the first argument is read. Defaults to the `USER` environment variable, then to `world`. |
| `--shout` | Upper-cases the greeting. |
| `--version` | Prints the crate version and exits. |
| `--times N` | Prints the greeting `N` times. Defaults to 1. |

```sh
$ cargo run -- Ada
Hello, Ada!
```

```sh
$ cargo run -- --shout Ada
HELLO, ADA!
```

```sh
$ cargo run -- --times 2 Ada
Hello, Ada!
Hello, Ada!
```

```sh
$ cargo run -- --version
0.1.0
```

With no name it greets whoever is signed in.

## Develop

This project uses the Rust 2021 edition.

```sh
cargo test
```

## Troubleshooting

**`error: --times value must be a number, got "abc"`**

`--times` needs a whole number of zero or more. If the value is anything else, such as `abc`, `-1` or `2.5`, the program prints this error to stderr and exits with status 2 without greeting anyone. Pass a plain number, for example `--times 3`. A `--times` with no value after it also fails, with `--times requires a value`.

**The greeting says `Hello, world!` when I gave a name**

An empty or whitespace-only name, such as `cargo run -- ""`, is treated as no name and the greeting uses `world`. It does not fall back to the `USER` environment variable; that only happens when no name argument is given at all. Check that your shell is not expanding the name to an empty string, for example from an unset variable like `"$NAME"`.

I added a ## Output section to README.md, right after Usage. It shows cargo run -- Grace and its output, Hello, Grace!. I changed nothing else.

I ran the check from the issue and it passes. I didn't run the other tests.

If #42 or #7 merge first and change the greeting, this example will need updating to match.

This run cost $0.0335 over 4 turns.
