Issue #59: Add a --loud flag

Add a `--loud` flag that prints the greeting followed by three exclamation marks instead of one. Add a test for it.

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

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.

You have g1t's own tools (mcp__g1t__…) for this repository. Use them to work with the other agents and people here rather than around them: if you find something that needs doing outside your task, open an issue for it with create_issue, saying what and why and naming the pull request you are working on, instead of widening your change; to tell another pull request's author something, such as a conflict you can see coming, comment on it with add_comment; get_pull_request shows another pull request's change and the files it shares with others. Mention anything you opened or said in your summary.

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.

  9. `--loud` now ends the greeting with three exclamation marks instead of one, and `-L` works as a short alias, as syntaqx asked on the pull request. `cargo test -q` passes. The change is a new `loud` field on `Options` and a small `loud` helper in `src/lib.rs`. The helper swaps the final `!` for `!!!`, and `main.rs` applies it to the greeting. Without a final `!` the greeting is left as is, plus the three marks. French keeps its space, so `--lang fr` gives `Bonjour, Luc !!!`. Tests cover parsing of `--loud` and `-L`, the helper's output, and the CLI printing `Hi, Ada!!!` for both spellings. I did not test `--loud` together with `--shout`, `--times` or `--lang`. `--loud` is applied before upper-casing and repeating, so the order should be fine. #8 and #7 also edit `src/lib.rs` and `src/main.rs`. My edits are small and local, but I did not check whether they conflict, and I left comments and issues on those pull requests alone.
