xtask/tests/siblings_verb.rs

//! **`cargo xtask siblings` still exists, succeeds and does nothing else.**
//!
//! monetize's `cargo xtask build-guests` runs it in this sibling before it builds
//! `crates/gunnar-monetize-guest` with `cargo build --locked` (2026-10-25). Until G-B7 it switched
//! the estate's sibling patches on (`.cargo/siblings.toml`); since G-B7 the guest's own manifest
//! carries the patches its lock takes, so there is nothing to switch, but the verb stays so that
//! caller keeps working.
