Initial commit - Project start (July 17, 2025)

Original: feat: enhance security logging and ensure rate limit blocks are properly tracked - Add comprehensive logging for rate limit blocks with full request details - IP address (with proper proxy detection), user agent, headers, timestamps - Rate limit info (current count, limit, remaining, reset time) - Separate tracking for auth vs general endpoints - Enhance authentication failure logging - JWT validation failures with detailed error info - Admin auth attempts without token - Failed token validation with user context - All events include IP, path, method, user agent - Improve Winston logger configuration for production - Add automatic log rotation (10MB errors, 50MB combined) - Create separate security.log for auth/rate limit events - Ensure logs directory exists automatically - Add structured JSON format for log aggregation - Support container logging with LOG_TO_CONSOLE env var - Create comprehensive documentation - Security logging guide with examples - Monitoring recommendations - Configuration reference - Add test script to verify logging functionality All rate limit settings remain configurable via admin panel: - Window duration, max requests, auth limits - Skip authenticated requests option - Public endpoints only option 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
