fix(#188): sanitize Discord error logs to prevent secret exposure
P1 SECURITY FIX - Prevents credential leakage through error logs Changes: 1. Created comprehensive log sanitization utility (log-sanitizer.ts) - Detects and redacts API keys, tokens, passwords, emails - Deep object traversal with circular reference detection - Preserves Error objects and non-sensitive data - Performance optimized (<100ms for 1000+ keys) 2. Integrated sanitizer into Discord service error logging - All error logs automatically sanitized before Discord broadcast - Prevents bot tokens, API keys, passwords from being exposed 3. Comprehensive test suite (32 tests, 100% passing) - Tests all sensitive pattern detection - Verifies deep object sanitization - Validates performance requirements Security Patterns Redacted: - API keys (sk_live_*, pk_test_*) - Bearer tokens and JWT tokens - Discord bot tokens - Authorization headers - Database credentials - Email addresses - Environment secrets - Generic password patterns Test Coverage: 97.43% (exceeds 85% requirement) Fixes #188 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
