mockforge-collab 0.3.92

//! Bridge between mockforge-collab and mockforge-core workspace types
//!
//! This module provides conversion and synchronization between:
//! - `TeamWorkspace` (collaboration workspace with metadata)
//! - `Workspace` (full mockforge-core workspace with mocks, folders, etc.)
