//! Port of enhanced_integrated_swarm.py (109 lines).
//!
//! The original Python module depended on `lean_unified_shim`, which has been
//! removed from the repository.  This module provides the same public surface
//! but returns a structured manifest that callers can use to trigger the actual
//! `lake build` pipeline in `0-Core-Formalism/lean/Semantics/`.
