 * Anonymization rules:
 * - Supabase URL → https://*.supabase.co
 * - API keys → configured: true/false
 * - IP addresses → stripped
 * - Scar/session/decision content → counts only
 * - Error messages → URLs/keys stripped via regex
 * - Cache paths → normalized to ~/.gitmem/...
 * - Hostnames → excluded
 * - Platform/Node version → included
