/**
 * AI change-risk score.
 *
 * Combines memory status, confidence, evidence, file scope, and critical-area
 * membership into a 0–100 risk score for a set of changed files. The score is
 * designed to surface changes that need human review before merge.
 *
 * Factors:
 *  - Violation severity (fail > warn)
 *  - Memory kind (GUARDRAIL/FAILED_APPROACH > INVARIANT > CONVENTION > other)
 *  - Memory status (REFUTED > STALE > UNVERIFIED > VERIFIED)
 *  - Confidence (lower confidence → higher risk)
 *  - Evidence count (more evidence → lower risk for that memory)
 *  - Critical-area membership (adds a flat risk bonus)
 *  - Number of changed files (broader changes → higher risk)
