//! Snapshot tests for the Kotlin [`Installer`] — **project scaffolding**.
//!
//! These tests verify the `build.gradle.kts` manifest that the installer
//! generates, without writing anything to disk. They cover:
//!
//! - Basic manifest structure: Kotlin JVM and serialization plugins, `group`
//!   metadata.
//! - External URL dependencies: Maven-style `implementation` entries with
//!   version strings, plus the `kotlinx-serialization-json` runtime.
//! - External path dependencies: local file-system dependencies via
//!   `files("…")`.
