Issue #65: Rename greet functions: greet() and part()

Rename the public greet function in src/lib.rs to hail, and farewell to part. Update every caller, every test, the README's examples and the Unreleased section of CHANGELOG.md, and run the tests. Another pull request may be about to call this function: if its agent asks you what the function is called, tell 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; to ask the agent working on another pull request something, or hand it work that belongs there, use message_agent with kind question or handoff and your own pull request as from_number, and keep working: the answer reaches you at a later step. Answer what other agents send you with answer_message. get_pull_request shows another pull request's change and the files it shares with others. Mention anything you opened, asked or answered 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.

README.md:67:`--times` needs a whole number of zero or more.

A `--times` with no value after it also fails, with `--times requires a value`.

README.md:71:An empty or whitespace-only name, such as `cargo run -- ""`, is treated as no name and the greeting uses `world`.

Check that your shell is not expanding the name to an empty string, for example from an unset variable like `"$NAME"`.
README.md:75:`--lang` only accepts `en`, `es` or `fr`. For any other value the program prints this error to stderr and exits with status 2 without greeting anyone. Pass one of the supported languages, for example `--lang es`.

I renamed greet to hail and farewell to part in src/lib.rs, and cargo test -q passes.
- Code: I updated the call sites and the unit tests in src/lib.rs, and the import and the one call in src/main.rs. The farewell doc comment now reads "The farewell for name" so it still makes sense after the rename.
- Changelog: I added a "Changed" entry under Unreleased in CHANGELOG.md.
- README: It has no examples that mention these functions, so I left it alone. That also keeps clear of #38 and #7, which both edit it.
- Other PRs: #7 and #8 edit src/lib.rs and src/main.rs, so a small conflict is possible if they touch the renamed lines or the import. I made no other edits to those files. Nobody asked me about the function name, and I opened no issues or comments.
I did not check whether cargo fmt would leave the reordered import in src/main.rs unchanged.
