//! Packaging entrypoint test: assert both `flowmark` and `flowmark-rs` binaries
//! point to the same source path with the same required features.
//!
//! Ported from Python: `tests/test_packaging_entrypoints.py` (v0.6.5, commit `d866c08`).
//! Python's test asserts `[project.scripts].flowmark` and `flowmark-py` both resolve
//! to `flowmark.cli:main`. The Rust analog asserts the two `[[bin]]` entries in
//! Cargo.toml share `path` and `required-features`.
