//! Pattern lowerers for different loop constructs
//!
//! Phase 2: Extracted from control_flow.rs
//! - Pattern 1: Simple While Loop (pattern1_minimal.rs)
//! - Pattern 2: Loop with Conditional Break (pattern2_with_break.rs)
//! - Pattern 3: Loop with If-Else PHI (pattern3_with_if_phi.rs)
//! - Pattern 4: Loop with Continue (pattern4_with_continue.rs) [Phase 194+]
//!
//! Phase 194: Table-driven router for pattern dispatch
//! - Router module provides table-driven pattern matching
//! - Each pattern exports can_lower() and lower() functions
//! - See router.rs for how to add new patterns
//!
//! Phase 193: AST Feature Extraction Modularization
//! - ast_feature_extractor.rs: Pure function module for analyzing loop AST
//! - High reusability for Pattern 5-6 and pattern analysis tools
//!
//! Phase 193-4: Exit Binding Builder
//! - exit_binding.rs: Fully boxified exit binding generation
//! - Eliminates hardcoded variable names and ValueId assumptions
//! - Supports both single and multi-carrier loop patterns
//!
//! Phase 33-22: Common Pattern Infrastructure
//! - common_init.rs: CommonPatternInitializer for unified initialization
//! - conversion_pipeline.rs: JoinIRConversionPipeline for unified conversion flow
//!
//! Phase 171-172: Refactoring Infrastructure
//! - loop_scope_shape_builder.rs: Unified LoopScopeShape initialization (Issue 4)
//! - condition_env_builder.rs: Unified ConditionEnv construction (Issue 5)
//!
//! Phase 33-23: Pattern-Specific Analyzers (Stage 2)
//! - pattern4_carrier_analyzer.rs: Pattern 4 carrier analysis and normalization (Issue 2)
