🔧 Code Quality Improvements (Auto-Applied)

• usleep() → Sleep::usleep() - Laravel sleep helper
• sprintf() instead of string concatenation for complex messages
• Strict array comparison: count() > 0 → !== []
• Exception variable naming: $e → $throwable
• Consistent blank lines after control structures
• Auto-import of class names with unused import removal
