//! Embedding-based NLU router for the `wm` meta-tool.
//!
//! Replaces the 450-line keyword `if-else` chain with a data-driven TF-IDF
//! cosine similarity router. Each tool has a weighted keyword profile. Input
//! text is tokenized and compared against all profiles using cosine similarity.
//!
//! Advantages over the keyword chain:
//! - Scales to hundreds of tools without code changes (just add profiles)
//! - Handles partial matches and multi-word queries naturally
//! - Confidence score reflects actual semantic overlap, not arbitrary 0.9/1.0
//! - No ordering dependency — all profiles scored independently
