feat(joinir): Phase 172 - Trim pattern JoinIR lowering implementation
Implement actual MIR generation for Trim pattern loops, enabling
LoopBodyLocal variables to work through bool carrier promotion.
## Implementation (pattern2_with_break.rs)
- emit_whitespace_check(): Generate OR chain for whitespace comparison
- extract_substring_args(): Extract s, start from substring call
- Initial carrier generation: ch0 = s.substring(start, start+1)
- Whitespace check: is_ch_match0 = (ch0 == " " || "\t" || "\n" || "\r")
- ConditionEnv integration: Register carrier for JoinIR condition
- Break condition replacement: !is_ch_match instead of original ch checks
## Architecture
- Host MIR: substring calls, OR chain evaluation, BoxCall
- JoinIR: Only sees bool carrier for break control
- No new JoinIR instructions added
## Documentation
- phase172-trim-lowering-impl.md: Design and implementation details
- loop_pattern_space.md: Analysis of all loop pattern combinations
Test: Trim loops compile and generate JoinIR successfully
Build: 0 errors, clean compilation

feat(joinir): Phase 171-C-2 Trim pattern detection in LoopBodyCarrierPromoter
Implements the Trim pattern detection logic for carrier promotion:
- find_definition_in_body(): Iterative AST traversal to locate variable definitions
- is_substring_method_call(): Detects substring() method calls
- extract_equality_literals(): Extracts string literals from OR chains (ch == " " || ch == "\t")
- TrimPatternInfo: Captures detected pattern details for carrier promotion
This enables Pattern 5 to detect trim-style loops:
```hako
loop(start < end) {
local ch = s.substring(start, start+1)
if ch == " " || ch == "\t" || ch == "\n" || ch == "\r" {
start = start + 1
} else {
break
}
}
```
Unit tests cover:
- Simple and nested definition detection
- substring method call detection
- Single and chained equality literal extraction
- Full Trim pattern detection with 2-4 whitespace characters
Next: Phase 171-C-3 integration with Pattern 2/4 routing

feat(joinir): Phase 170-D-impl-1 LoopConditionScopeBox skeleton creation
Implement the LoopConditionScope analysis infrastructure for Pattern2/4 validation:
New module:
- src/mir/loop_pattern_detection/loop_condition_scope.rs (220 lines)
Types:
- CondVarScope enum: LoopParam, OuterLocal, LoopBodyLocal
- CondVarInfo: Variable name + scope classification
- LoopConditionScope: Collection of analyzed variables with helper methods
Box implementation (LoopConditionScopeBox):
- analyze(): Main entry point - extracts and classifies condition variables
- extract_vars(): Recursive AST traversal to find all variable references
- is_outer_local(): Heuristic for outer scope detection (phase 170-D simplified)
Helper methods:
- has_loop_body_local(): Check for unsupported loop-body variables
- all_in(): Validate scope compatibility
- var_names(): Get variable set
- add_var(): Add with deduplication
Tests: 5 unit tests for core functionality
Architecture: Refactored loop_pattern_detection.rs → loop_pattern_detection/mod.rs
for modular organization.
Build: ✅ Passed with no errors

feat(joinir): Phase 33-22 CommonPatternInitializer & JoinIRConversionPipeline integration
Unifies initialization and conversion logic across all 4 loop patterns,
eliminating code duplication and establishing single source of truth.
## Changes
### Infrastructure (New)
- CommonPatternInitializer (117 lines): Unified loop var extraction + CarrierInfo building
- JoinIRConversionPipeline (127 lines): Unified JoinIR→MIR→Merge flow
### Pattern Refactoring
- Pattern 1: Uses CommonPatternInitializer + JoinIRConversionPipeline (-25 lines)
- Pattern 2: Uses CommonPatternInitializer + JoinIRConversionPipeline (-25 lines)
- Pattern 3: Uses CommonPatternInitializer + JoinIRConversionPipeline (-25 lines)
- Pattern 4: Uses CommonPatternInitializer + JoinIRConversionPipeline (-40 lines)
### Code Reduction
- Total reduction: ~115 lines across all patterns
- Zero code duplication in initialization/conversion
- Pattern files: 806 lines total (down from ~920)
### Quality Improvements
- Single source of truth for initialization
- Consistent conversion flow across all patterns
- Guaranteed boundary.loop_var_name setting (prevents SSA-undef bugs)
- Improved maintainability and testability
### Testing
- All 4 patterns tested and passing:
- Pattern 1 (Simple While): ✅
- Pattern 2 (With Break): ✅
- Pattern 3 (If-Else PHI): ✅
- Pattern 4 (With Continue): ✅
### Documentation
- Phase 33-22 inventory and results document
- Updated joinir-architecture-overview.md with new infrastructure
## Breaking Changes
None - pure refactoring with no API changes
