    Issue #41: Greet with Hi instead of Hello

    Change the greeting from Hello, NAME! to Hi, NAME! (and HI, NAME! with --shout). Update the tests and every example in README.md to match.

    These commands must pass when you are done. Run them if the tools are installed:

    • cargo test -q
    • test "$(cargo run -q -- Ada)" = 'Hi, Ada!'

    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:

    • #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.

    The greeting is now Hi, NAME!, and HI, NAME! with --shout. The change is one format string in src/lib.rs, plus the unit tests, the CLI tests in tests/cli.rs and the README examples that expected "Hello". That includes the troubleshooting entry that quotes the default Hello, world! greeting.

    cargo test -q passes, and cargo run -q -- Ada prints Hi, Ada!. I did not run the --shout path by hand beyond what the tests cover.

    I left the crate name hello, the license and the contributing guide alone, since they refer to the project name rather than the greeting. The edits are single-line substitutions, so they should merge cleanly with the pending README and src/lib.rs pull requests. The Spanish and French greeting work in #7 and #8 may need small follow-up edits where it touches the same greeting lines.
