Supplier Modern Slavery Collect

Use to assess modern-slavery risk for each ready supplier in the enumerate manifest, writing modern-slavery-risk-assessment.json beside identity.json. MUST run bundled lib/ms_collect.py — never regenerate the collector. Manifest.suppliers is an array (not a map). Discovers the supplier's statement and adverse news via Talos, scores governance and operational mitigation via LLM, combines with deterministic geographic/industry inherent risk. No cortex_search.
