docs: Phase 260 P0.3 完了記録 + 既知FAIL SSOT更新

**10-Now.md 更新**:
- Phase 260 P0.2/P0.3 完了記録追加(15モジュール、約3941行、53単体テスト)
- Current First FAIL を "P0.3完了後" に更新
- 既知FAILに "Phase 260 scope外" を明記
- 期待/実際の詳細追加
- 次アクション: 機能側Phase(Pattern2 LoopBodyLocal promotion)へ

**phase-260/README.md 更新**:
- Status: P0.3 完了 
- P0.2/P0.3 進捗セクション追加(commit履歴、成果)
- モジュール分割の責務一覧(Utilities 7 + Handlers 8)
- SSOT維持確認項目(jump_args直参照ゼロ、out_edges()/edge_args_to() SSOT維持、PHI preservation、Phase metadata保持)

Phase 260 完全達成: CFG基盤整備完了、今後は機能側Phaseへ

## Current First FAIL (SSOT)
- **After Phase 260 P0.1**: `core_direct_array_oob_set_rc_vm / Stage-B compile / JoinIR Pattern2 LoopBodyLocal(seg)`
- **After Phase 260 P0.3**: `core_direct_array_oob_set_rc_vm / Stage-B compile / JoinIR Pattern2 LoopBodyLocal(seg)`
### Next FAIL Details
### FAIL Details (既知・Phase 260 scope外)
- **Test**: `core_direct_array_oob_set_rc_vm`
- **Status**: **既知 / Phase 260 scope外**JoinIR Pattern2 LoopBodyLocal promotion 未実装)
- **Phase**: StageB compile (`stageb_compile_to_json`)
- **Error**: `[cf_loop/pattern2] Cannot promote LoopBodyLocal variables ["seg"] ... [pattern2/body_local_slot/contract/not_readonly]`
- **Error**: `[cf_loop/pattern2] Cannot promote LoopBodyLocal variables ["seg"]: No promotable pattern detected (tried A-3 Trim, A-4 DigitPos); read-only-slot rejected: [joinir/freeze] [pattern2/body_local_slot/contract/not_readonly] 'seg' must be read-only (assignment detected in loop body)`
- **Expected**: Stage-B compile succeeds (bundle_resolver loop compiles)
- **Actual**: MIR compilation error (LoopBodyLocal "seg" cannot be promoted - A-3/A-4 patterns not detected)
- **Reproduce**:
```bash
./tools/smokes/v2/run.sh --profile quick
# または
bash tools/smokes/v2/profiles/quick/core/core_direct_array_oob_set_rc_vm.sh
```
- **Note**: Pattern2 の LoopBodyLocal promotionA-3 Trim / A-4 DigitPosに依存しており、StageB の bundle_resolver 系のループで露出している。
- **Root Cause**: Pattern2 の LoopBodyLocal promotionA-3 Trim / A-4 DigitPosに依存しており、StageB の bundle_resolver 系のループで露出している。
- **Next Action**: **Phase 260 完了**P0.3まで完了)→ **今後は機能側のPhaseへ**Pattern2 LoopBodyLocal promotion 機能実装)
- **分類**: JoinIR Pattern2 機能拡張compiler機能側、CFG基盤整備は完了

- P0: MIR terminator の edge-args 併存導入(読む側 SSOT を `out_edges()`/`edge_args_to()` へ寄せた)
- P0.1: legacy layout の未設定を禁止verify fail-fast terminator 直代入を `set_terminator*()` へ寄せた
