Core3 risk intelligence API

Core3 risk intelligence integration for tracking Probability of Loss (PoL) scores across crypto projects.

Core3 (formerly CER.live) provides risk ratings across six categories: security, financial, operational, reputational, regulatory, and dependency. This module fetches and stores risk data in a local DuckDB database for historical tracking.

Features:

• Rate-limited API session with retry logic

• DuckDB storage with incremental sync (two-phase backfill + ranged updates)

• Parallel project scanning with joblib

• Raw JSON payload storage for future re-extraction
