1//! Patterns command - Detect design patterns and coding conventions
2//!
3//! Analyzes a codebase to detect patterns including:
4//! - Soft delete patterns
5//! - Error handling patterns
6//! - Naming conventions
7//! - Resource management patterns
8//! - Validation patterns
9//! - Test idioms
10//! - Import patterns
11//! - Type coverage
12//! - API conventions
13//! - Async patterns
