44b20bfe28 fix(mir): Complete ScopeContext migration (Phase 2-4 補完) 
Phase 2-4 で移行漏れがあったファイルを修正。

## Changes
- Fixed all remaining compilation errors from incomplete Phase 2-4 migration
- Updated access sites to use scope_ctx.* for 7 legacy fields:
  1. current_function → scope_ctx.current_function
  2. lexical_scope_stack → scope_ctx.lexical_scope_stack
  3. if_merge_stack → scope_ctx.if_merge_stack
  4. debug_scope_stack → scope_ctx.debug_scope_stack
- Updated visibility of ScopeContext to pub(in crate::mir) for cross-module access
- Removed dual-write legacy code in lexical_scope.rs, builder.rs
- Updated documentation comments in phi_helpers.rs

## Files Modified (20 files)
Core access migration:
- src/mir/builder/method_call_handlers.rs
- src/mir/builder/control_flow/joinir/routing.rs
- src/mir/builder/control_flow/joinir/merge/loop_header_phi_builder.rs
- src/mir/builder/if_form.rs
- src/mir/builder/ops.rs (4 occurrences)
- src/mir/builder/observe/resolve.rs (2 occurrences)
- src/mir/builder/observe/ssa.rs
- src/mir/builder/receiver.rs
- src/mir/loop_api.rs (3 occurrences)
- src/mir/region/observer.rs (3 occurrences)
- src/mir/utils/control_flow.rs
- src/mir/utils/phi_helpers.rs (4 occurrences + docs)

Dual-write removal:
- src/mir/builder/vars/lexical_scope.rs (push/pop/declare)
- src/mir/builder.rs (if_merge, debug_scope, emit_instruction)

Visibility updates:
- src/mir/builder/scope_context.rs (struct + fields)

## Tests
- cargo build --release: SUCCESS (0 errors, 191 warnings)
- Phase 2-4 migration now fully complete
- Note: Test failures exist but are unrelated (Phase 2-5 binding_map issue)

Phase 2-4 now fully complete ✅

2db8ff72d0 refactor(mir): Remove CoreContext legacy fields (Phase 2-2/7) 
完全移行→削除の安全順序（Option C）に従い、CoreContext の
deprecated フィールドと sync helpers を完全削除。

## Changes
- Migrated all access sites to core_ctx.* (SSOT allocators)
  - utils.rs: value_gen (3 sites), block_gen (1 site), temp_slot_counter (1 site)
  - loop_api.rs: block_gen (1 site)
  - phi_helpers.rs: value_gen (1 site)
  - builder.rs: sync helpers (2 methods), test assertions (2 sites)
- Removed 5 deprecated fields from builder.rs
  - value_gen: ValueIdGenerator
  - block_gen: BasicBlockIdGenerator
  - next_binding_id: u32
  - temp_slot_counter: u32
  - debug_join_counter: u32
- Removed sync helper calls (allocate_binding_id, debug_next_join_id)
- Removed field initializations from MirBuilder::new()
- Maintained Phase 136 P0 SSOT structure (next_value_id() remains as high-level API)

## Tests
- cargo build --release: PASS
- cargo test --release --lib: 1029 passed (4 pre-existing failures)
- Deprecation warnings: 435 → 456 (+21)
  Note: Warnings increased due to remaining deprecated field *uses* being exposed
  after removing the field *definitions*. This is expected during migration.

## Code metrics
- Net reduction: 40 lines (-56 removed, +16 modifications)
- Files changed: 4 (builder.rs, utils.rs, loop_api.rs, phi_helpers.rs)

Phase 2 Progress: 2/7 contexts complete (MetadataContext ✅, CoreContext ✅)

a898e99310 refactor(mir): Remove MetadataContext legacy fields (Phase 2-1/7) 
完全移行→削除の安全順序（Option C）に従い、MetadataContext の
deprecated フィールドと sync helpers を完全削除。

## Changes
- Migrated all access sites to metadata_ctx.* (builder methods)
  - current_span → metadata_ctx.current_span() / set_current_span()
  - source_file → metadata_ctx.current_source_file() / set_source_file() / clear_source_file()
  - hint_sink → metadata_ctx.hint_scope_enter/leave/join_result()
  - current_region_stack → metadata_ctx.push_region/pop_region/current_region_stack()
- Removed 4 deprecated fields from MirBuilder
  - current_span, source_file, hint_sink, current_region_stack
- Removed 2 sync helpers
  - sync_metadata_ctx_to_legacy(), sync_legacy_to_metadata_ctx()
- Updated 10 files with direct field accesses

## Files Modified
- src/mir/builder.rs: -56 lines (fields + sync helpers + initialization)
- src/mir/builder/exprs.rs: metadata_ctx.set_current_span()
- src/mir/builder/exprs_peek.rs: metadata_ctx.current_span()
- src/mir/builder/if_form.rs: metadata_ctx.current_span()
- src/mir/builder/phi.rs: metadata_ctx.current_span()
- src/mir/builder/stmts.rs: metadata_ctx.set_current_span()
- src/mir/builder/utils.rs: metadata_ctx.current_span()
- src/mir/loop_api.rs: metadata_ctx.current_span()
- src/mir/region/observer.rs: metadata_ctx.push/pop_region()
- src/mir/utils/phi_helpers.rs: metadata_ctx.current_span()

## Tests
- cargo build --release: SUCCESS (1m 10s)
- cargo test --release --lib: 1029 PASS, 4 FAIL (pre-existing)
- Deprecation warnings: 469 → 435 (-34 warnings)

## Verification
✅ No direct access to removed fields (grep count: 0)
✅ No sync helper calls (grep count: 0)
✅ Build success
✅ MetadataContext is now complete SSOT (二重管理解消)

Phase 2 Progress: 1/7 contexts complete (MetadataContext ✅)

eee3dfaa83 refactor(builder): 箱理論リファクタリング Phase 1完了 
🎯 builder_calls.rs (982行) を箱理論で責務別にモジュール分割

## 成果
✅ builder_calls.rs: 982行 → 766行（-216行、22%削減）
✅ calls/lowering.rs: 354行（新規、箱理論6段階パターン）
✅ calls/utils.rs: 45行（新規、ユーティリティ統一）
✅ ビルド・テスト完全成功（0エラー）

## 箱理論の実装
1. 責務ごとに箱に分離:
   - lowering: 関数lowering専用
   - utils: ユーティリティ統一
   - emit/build: Phase 2で実装予定

2. 境界を明確に:
   - mod.rs で公開インターフェース定義
   - pub(in crate::mir::builder) で適切な可視性制御

3. いつでも戻せる:
   - 段階的移行、各ステップでビルド確認
   - 既存API完全保持（互換性100%）

4. 巨大関数は分割:
   - lower_static_method_as_function: 125行 → 6段階に分解
   - lower_method_as_function: 80行 → 6段階に分解

## 箱理論6段階パターン
1. prepare_lowering_context - Context準備
2. create_function_skeleton - 関数スケルトン作成
3. setup_function_params - パラメータ設定
4. lower_function_body - 本体lowering
5. finalize_function - 関数finalize
6. restore_lowering_context - Context復元

## ファイル構成
src/mir/builder/
├── calls/
│   ├── mod.rs           # 公開インターフェース
│   ├── lowering.rs      # 関数lowering（354行）
│   └── utils.rs         # ユーティリティ（45行）
└── builder_calls.rs     # 削減版（766行）

## 次のステップ
Phase 2: emit.rs 作成（~500行移行）
Phase 3: build.rs 作成（~350行移行）
最終目標: builder_calls.rs を200行以内に
