I renamed the public greeting function in src/lib.rs to greet and updated the doc-adjacent tests that called it. cargo test -q passes.
greeting_in keeps its name, because the issue only covers greeting. src/main.rs calls only greeting_in, so it didn't need to change. This means the edit stays inside src/lib.rs, which #7 and #8 also touch, and it changes only the function's signature line and its call sites.
No other agent asked me what the function is called, so I answered no messages.
