//! CLI-level tests for `flowmark --install-skill --surfaces` parsing and the
//! project-root git recommendation.
//!
//! Ported from Python: `test_skill.py::TestInstallSkillCli` and the git-recommendation
//! cases in `TestInstallSkill`. These drive the built binary with a temp working
//! directory, the Rust analog of Python's `monkeypatch.chdir` + `capsys`.
