//! Purpose: suite-local fixtures and CLI helpers for `queue_search_test`.
//!
//! Responsibilities:
//! - Create disposable repos from the cached git+`.ralph/` integration scaffold.
//! - Centralize queue/done fixture writes for search scenarios.
//! - Provide small helpers for invoking `ralph queue search` and decoding JSON output.
//!
//! Scope:
//! - Helpers used only by `crates/ralph/tests/queue_search_test.rs`.
//!
//! Usage:
//! - Call `SearchRepo::new()` per test.
//! - Seed queue/done state with `write_queue()` / `write_done()`.
//! - Use `search_json()` for JSON-output assertions and `search()` for raw stdout/stderr checks.
//!
//! Invariants/Assumptions:
//! - Fixtures use cached seeded repo scaffolding instead of repeating `git init` + `.ralph` bootstrap.
//! - Helpers preserve end-to-end CLI coverage by invoking the real `ralph` binary.
//! - JSON assertions are only valid when the caller passes `--format json`.
