feat(joinir): Phase 78 - BindingId infrastructure for promoted carriers (dev-only)

Browse Source 
Phase 78 adds infrastructure to assign BindingIds to synthetic promoted
carriers (e.g., is_digit_pos, is_ch_match), enabling type-safe promoted
variable lookup without string-based naming conventions.

Key Changes:
1. CarrierVar.binding_id field (dev-only):
   - Added Option<BindingId> to track BindingId for each carrier
   - Updated all constructors and struct instantiations

2. CarrierBindingAssigner Box (new file, 273 lines):
   - Allocates BindingIds for promoted carriers via builder.allocate_binding_id()
   - Records original → promoted mapping in promoted_bindings
   - Sets binding_id field on promoted CarrierVar
   - Includes 3 comprehensive unit tests

3. ConditionEnv.register_carrier_binding() (new method):
   - Registers carrier BindingId → ValueId mappings
   - Enables type-safe lookup via binding_id_map

4. Logging cleanup:
   - Gated 6 eprintln! statements with NYASH_JOINIR_DEBUG
   - Unified logging tags to [binding_pilot/*]

Design Decisions:
- Promoters create CarrierInfo, lowering code assigns BindingIds
- CarrierBindingAssigner called from Pattern2/4 lowering (has builder access)
- Clear documentation prevents misuse (promoters lack builder access)

Files modified (18):
- carrier_info.rs: binding_id field added to CarrierVar
- carrier_binding_assigner.rs: New Box for BindingId allocation
- condition_env.rs: register_carrier_binding() method
- mod.rs: Module exports
- pattern2_with_break.rs, pattern4_with_continue.rs: Updated for binding_id
- loop_body_*_promoter.rs: Logging cleanup + binding_id in structs
- phase78-bindingid-promoted-carriers.md: Architecture documentation

Tests: 970/970 PASS (zero regressions)
Status: Infrastructure complete, integration deferred to Phase 79

Next Phase: Wire CarrierBindingAssigner in Pattern2/4 lowering + E2E tests

38. **Follow-up（コミット済み✅ `0aad016b` 2025-12-13）**: legacy promoted lookup の deprecation warning を局所化
- `ScopeManager::lookup` 内の legacy 呼び出しを `#[allow(deprecated)]` で包み、全ビルドでの警告を抑制
39. **Phase 78-A（コミット済み✅ `10e78fa3` 2025-12-13）**: PromotedBindingRecorder の整理（dev-only）
- binding_map の受け渡しを Box 化し、検出器（Detector）と記録（Recorder）の責務を分離。
- 以後の “BindingId を供給する導線” の議論を単純化するための整地。
40. **Phase 79（コミット済み✅ `48bdf2fb` 2025-12-13）**: Detector/Recorder separation + BindingMapProvider
- `BindingMapProvider` を導入し、`#[cfg(feature="normalized_dev")]` の散在を抑制する方向へ。
---
## 🚀 次フェーズ候補（Phase 78+）
### Phase 78（dev-only）: BindingId Migration を “完結” に寄せる
- Pattern3/4 で binding_id を供給する導線を追加し、name fallback を観測可能に縮退
- Phase 77 で先送りした E2E tests 4本を追加（DigitPos/Trim/P3/P4）
- 余裕があれば: legacy name-based promoted lookup の撤去計画を docs に明記（削除は Phase 79 でも可）
### Phase 78-B（dev-only）: “promoted carriers” を BindingId で接続する（進行中）
- SSOT: `docs/development/current/main/phase78-bindingid-promoted-carriers.md`
- 目的: `BindingId(original)` → `BindingId(promoted)` → `ValueId(join)` の鎖を作り、name-hack 依存を減らす。
- 残タスク（優先順）:
1) ExprLowerer/ConditionLoweringBox の call-site で `lookup_with_binding()` を実際に使う（BindingId が効く状態にする）
2) Trim/Pattern4 側の “BindingId → join” を E2E で固定（DigitPos 以外の回帰ガード）
3) Pattern3/4 の本番導線へ拡張（P3 if-sum / P4 continue の binding 供給）
4) legacy name-based promoted lookup の縮退 → 撤去計画を docs に固定（削除自体は Phase 80+ でも可）

## Phase 78: BindingId for Promoted Carriers (dev-only)
### Goal
Make LoopBodyLocal promotion (DigitPos/Trim) **BindingId-aware** without relying on fragile name-based hacks like `format!("is_{}", name)`.
This phase introduces a dev-only identity link:
- `BindingId(original LoopBodyLocal)` → `BindingId(promoted carrier)` → `ValueId(join carrier param)`
### Problem
Promotion creates synthetic carrier names (例: `is_digit_pos`, `is_ch_match`) that do not exist as source-level bindings.
- `PromotedBindingRecorder` expects both original/promoted names in `MirBuilder.binding_map`.
- For promoted carriers this is not true by construction.
- For LoopBodyLocal variables, promotion can happen before their `local` is lowered, so the original name may also be absent.
### Solution (current state)
#### 1) CarrierVar gets optional BindingId (dev-only)
- `src/mir/join_ir/lowering/carrier_info.rs`
- `CarrierVar.binding_id: Option<BindingId>` (feature `normalized_dev`)
#### 2) CarrierBindingAssigner box
- `src/mir/join_ir/lowering/carrier_binding_assigner.rs`
- Ensures both sides have BindingIds:
- If `original_name` is missing in `builder.binding_map`, allocate a temporary BindingId.
- If `promoted_carrier_name` is missing, allocate a temporary BindingId.
- Records:
- `carrier_info.promoted_bindings[original_bid] = promoted_bid`
- `CarrierVar.binding_id = Some(promoted_bid)` for the promoted carrier
- Restores `builder.binding_map` after recording (synthetic names do not leak into the source map).
#### 3) Pattern2/Pattern4 wiring
- Pattern2 (break): `src/mir/builder/control_flow/joinir/patterns/pattern2_with_break.rs`
- Calls `CarrierBindingAssigner::assign_promoted_binding()` immediately after promotion.
- Registers `BindingId → ValueId` via `ConditionEnv.register_carrier_binding()` after carrier join_id allocation.
- Keeps legacy name-based aliasing (`digit_pos` → `is_digit_pos`) for now, but removes local “guess naming” by using the promoted carrier name returned by the promoter.
- Pattern4 (continue): `src/mir/builder/control_flow/joinir/patterns/pattern4_with_continue.rs`
- Calls `CarrierBindingAssigner::assign_promoted_binding()` after promotion (analysis metadata only, since Pattern4’s current lowering path does not use JoinValueSpace params).
### Tests
- Unit test (dev-only): `src/mir/builder/control_flow/joinir/patterns/pattern2_with_break.rs`
- `phase78_promoted_binding_is_recorded_for_digitpos`
- Asserts:
- `promoted_bindings` has one mapping
- promoted carrier has `binding_id`
- `ConditionEnv.binding_id_map[promoted_bid] == promoted_carrier.join_id`
### Open Follow-ups (Phase 79+)
1. Wire `ScopeManager::lookup_with_binding()` into ExprLowerer/ConditionLoweringBox call-sites (so BindingId actually drives resolution).
2. Extend coverage to Trim and other promotion shapes (additional unit/E2E tests).
3. Shrink/remove legacy name-based promoted lookup (`resolve_promoted_join_id`) after call-sites consistently provide BindingId.
