tooling: embeddings unavailable without @huggingface/transformers

[carlos-alm]

Context

Discovered during Titan audit (phase: recon, date: 2026-04-02).

Description

Embeddings unavailable - @huggingface/transformers not installed. DRY checks will be grep-only.

Additional Context

codegraph embed -m minilm fails when the optional dependency is not installed. This limits the Titan pipeline's ability to detect code duplication via semantic search.
