cargo_bin_cmd! already returns an assert_cmd::Command, so the wrapper
failed clippy::useless_conversion under -D warnings.

+`cargo_bin_cmd!` expands to `assert_cmd::Command::new(...)`, so it needs
+no conversion — wrapping it in `Command::from` trips
+`clippy::useless_conversion`. Pass the bin target name explicitly: the
+no-argument form resolves the *package* name, which differs from the
+binary name whenever the crate is named something like `<name>-cli`.
+
+Integration tests are compiled with `--test`, so `cfg(test)` is set and
+the `#![cfg_attr(test, allow(...))]` panic-lint exemption from
+`scaffolding.md` applies here too.
