/// Testcontainer integration test for marketplace + git hooks workflow
///
/// This test validates the complete end-to-end workflow:
/// 1. Spins up Docker container with Rust toolchain
/// 2. Clones ggen repository
/// 3. Builds ggen from source
/// 4. Installs marketplace package (agent-editor)
/// 5. Sets up git hooks
/// 6. Makes file changes
/// 7. Commits changes to trigger git hooks
/// 8. Verifies ontology files are generated/updated
///
/// Run with: cargo test --test testcontainer_marketplace_git_hooks -- --ignored
