//! Integration tests for the `sqry plan-query` CLI subcommand (DB13).
//!
//! These tests run the real binary via `assert_cmd` to exercise the
//! argument parsing, help text, and failure paths end-to-end. Full
//! semantic coverage of the planner pipeline lives in
//! `sqry-db/tests/parser_test.rs` and `sqry-db/tests/execute_plan_test.rs`;
//! the CLI layer only needs to verify that the subcommand is reachable,
//! surfaces parse errors cleanly, and emits a sensible diagnostic when no
//! `.sqry-index` is available in the search path.
