Issue #67: Add a --wave flag

Add a `--wave` flag that prints `o/` on a line after the greeting, built on the library's greeting function. Another pull request is renaming that function right now: before you depend on its name, ask that pull request's agent which name to use (with message_agent, kind question), and use its answer.

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:

- #66 Rename greet functions: greet() and part() (for issue #65), 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.

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.

  9. I added a `--wave` flag that prints `o/` on its own line after the greeting. `cargo test -q` passes, and running `--wave Ada` prints `Hi, Ada!` then `o/`. I added a `wave: bool` option, the parsing for the flag, a small `wave()` helper in `src/lib.rs` that returns `"o/"`, and tests for both. `src/main.rs` prints it after the greeting lines. It prints before the `--bye` goodbye when both flags are given, which is a choice the issue didn't specify. The greeting itself is untouched. `main.rs` already builds it with `greeting_in`, which the rename in #66 does not touch. So the flag doesn't depend on the name that PR is changing. I asked the agent on #66 which name to use. It had not answered when I finished, and the question was still undelivered. Its PR renames `greet` to `hail` and `farewell` to `part`, though its title says `greet()` and `part()`. Because I didn't use either name, #66 and this PR should merge without a conflict in the code. Both change `src/lib.rs` and `src/main.rs`, but in different places. I did not check that against a merged tree. I opened no issues or comments.

These acceptance checks were run against your change in a clean sandbox and failed.

  15. Merged in the latest main before starting; src/main.rs conflict.
  16. Bashgit status --short && grep -n -B3 -A25 '<<<<<<<' src/main.rs; grep -rn '<<<<<<<\|>>>>>>>' . --include=* -l 2>/dev/null | grep -v target | head

  17. Main renamed farewell to part. Let me see the rest and lib.rs.

  18. Bashsed -n 28,80p src/main.rs; grep -n 'farewell\|part\b\|fn ' src/lib.rs | head -40
  19. Bashpython3 - <<'E' import re s=open('src/main.rs').read() s=re.sub(r'<<<<<<< HEAD\n.*?>>>>>>> \w+\n','use hello::{greeting_in, loud, parse_args, part, shout, wave};\n',s,flags=re.S) open('src/main.rs','w').write(s) E git add src/main.rs && cargo test -q 2>&1 | tail -15
  20. Bashcargo test -q 2>&1 | grep -n 'test result\|FAIL\|error' ; git commit -qm "Merge main into wave flag branch Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>" && git log --oneline | head -2

  21. I resolved the merge conflict in `src/main.rs` and committed it. `cargo test -q` now passes: 33 unit tests and 12 integration tests, with no failures. **Merge conflict.** The conflict was in the `use hello::{…}` line. Main had renamed the farewell function to `part` (and `greeting` to `hail`), and my branch added `wave`. I kept both, so the line is now `use hello::{greeting_in, loud, parse_args, part, shout, wave};`. No conflict markers remain. **Failing check.** The check failed because of the conflicted tree. With the merge resolved, it passes locally. **Which greeting name to use.** I did not send a new question to #66's agent. Its rename has already landed on main as `hail` and `part`, so the question is settled. `--wave` still doesn't call `hail`: `main.rs` builds the greeting with `greeting_in`, which the rename didn't touch. I didn't open any issues or comments. I did not run `--wave` end to end after the merge, and I did not check this branch against #7, #8 or #38. The sandbox acceptance check also hasn't run on the merged result.

  22. This run cost $0.1301 over 5 turns.
