Apply critical security fixes and major improvements to all scripts
Security (CRITICAL): - Add .env.example with strong password generation instructions - Fix path traversal validation in restore.sh (now detects all .. patterns) - Secure .env loading with set -a/set +a in all scripts - Add logs/ to .gitignore to prevent credential leaks Backup & Restore (IMPORTANT): - Add file locking system to prevent concurrent backups - Add disk space verification before backup operations - Generate SHA256 checksums for all backups - Verify checksums before restoration - Create safety database backup before restore - Implement comprehensive logging to ./logs/ directory - Fix BACKUP_RETENTION_DAYS inconsistency - Replace dangerous find -delete with safe iteration Update & Recovery: - Backup docker-compose.yml before updates with auto-rollback - Add version display before/after updates - Increase timeouts to 120s for slow containers - Dynamic backup suggestion in recover.sh Compatibility: - Add Docker Compose v2 support with v1 fallback in all scripts - Standardized log() function across all scripts New Features: - Add check-health.sh: comprehensive system health monitoring - Add SECURITY.md: complete security documentation - Update Makefile with check-health and recover commands - Centralized logging with timestamps and levels 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
