tomoaki be4de67601 fix(joinir): improve Pattern3 classification to exclude simple conditional assignment (Phase 264 P0)
Problem:
- Pattern3 heuristic was too conservative: detect_if_in_body() returned
  true for ANY if statement, causing simple conditional assignments to be
  misclassified as Pattern3IfPhi
- Example: `if i == 0 then seg = "first" else seg = "other"` was routed
  to Pattern3, but Pattern3 only handles if-sum patterns like
  `sum = sum + (if x then 1 else 0)`
- This caused loops with conditional assignment to fail Pattern3 check
  and exhaust all routing paths

Solution (Conservative, Phase 264 P0):
- ast_feature_extractor.rs:
  - detect_if_else_phi_in_body(): Always return false
  - has_if = has_if_else_phi (don't use detect_if_in_body())
- loop_pattern_detection/mod.rs:
  - Add has_if_sum_signature() (returns false for P0)
  - has_if_else_phi = carrier_count > 1 && has_if_sum_signature(scope)

Effect:
- Simple conditional assignment loops now fall through to Pattern1 
- Pattern3 misrouting prevented 

Results:
- Lib tests: 1368/1368 PASS (no regression)
- Minimal repro: phase264_p0_bundle_resolver_loop_min.hako PASS 
- Quick smoke: 45/46 (unchanged - complex BundleResolver loop needs P1)

Phase 264 P1 TODO:
- Implement accurate if-sum signature detection (AST/CFG analysis)
- Support complex nested loops in Pattern2 or new pattern

Phase 命名規則

  • ファイル名: phase-<N>-<title>/ (例: phase-131/)
  • 文書名: <N>-<NN>-<topic>.md (例: 131-11-case-c-summary.md)
    • Phase 番号で自然にソート可能
    • 同一 Phase 内で段階的に追跡可能

作成ルールSSOT

詳しくは ../DOCS_LAYOUT.md を参照。

  • 置き場所: phases/phase-<N>/ 配下のみ
  • 内容: Phase の実装記録・進捗・チェックリスト・検証結果
  • 避けるべき: 複数 Phase で参照される設計・アーキテクチャ(→ design/ へ)
