feat(anf): Phase 146/147 - Loop/If Condition ANF with Compare support

## Phase 146 P0: ANF Routing SSOT Unified

**Goal**: Unify ANF routing in `lower_expr_with_scope()` L54-84, remove legacy lowering

**Changes**:
- expr_lowerer_box.rs: Added scope check (PureOnly → skip ANF, WithImpure → try ANF)
- post_if_post_k.rs: Removed legacy inline lowering (L271-285), added `lower_condition_legacy()` helper
- contract.rs: Already had `CondLoweringFailed` out-of-scope reason

**Test Results**:  Phase 146 P0 smoke (exit 7), 0 regressions

## Phase 146 P1: Compare Operator Support

**Goal**: Enable ANF for condition expressions with Compare operators

**Changes**:
- joinir_dev.rs: Added `anf_allow_pure_enabled()` (HAKO_ANF_ALLOW_PURE=1)
- expr_lowerer_box.rs: PureOnly scope ANF support (L56-66)
- execute_box.rs: Compare operator support (+122 lines)
  - `execute_compare_hoist()`, `execute_compare_recursive()`, `ast_compare_to_joinir()`
  - Extended `normalize_and_lower()` for Compare

**Test Results**:  Phase 146 P1 smoke (exit 7 with flags), 0 regressions

## Phase 147 P0: Recursive Comparison ANF

**Goal**: Extend recursive ANF to Compare operators

**Changes**:
- contract.rs: Added `AnfParentKind::Compare` variant
- plan_box.rs: Compare case in BinaryOp routing (L68-79, L134-139)
  - Distinguishes Compare vs arithmetic BinaryOp

**Benefits**: Enables recursive ANF for comparisons
- `s.length() == 3` → `t = s.length(); if (t == 3)` 
- `s1.length() < s2.length()` → `t1 = s1.length(); t2 = s2.length(); if (t1 < t2)`

# Phase 146: Loop/If Condition ANF Implementation
**Status**: P0 in progress / P1 planned
**Date**: 2025-12-19
**Context**: Phase 145 P0/P1/P2 complete (ANF infrastructure). Phase 146/147 adds condition expression support.
## Overview
Phase 146 enables ANF (A-Normal Form) transformation for loop and if conditions, extending Phase 145's compound expression support to control flow conditions.
## Phase 146 P0: ANF Routing SSOT 統一
**Goal**: Add scope check to ANF routing, unify SSOT, remove legacy inline lowering.
### Implementation
1. **expr_lowerer_box.rs**: Added scope check to ANF routing (L54-79)
- `PureOnly` scope: Skip ANF (P1 will enable)
- `WithImpure` scope: Try ANF (Phase 145 behavior)
2. **post_if_post_k.rs**: Replaced legacy inline lowering with SSOT (L271-285)
- Use `NormalizedExprLowererBox::lower_expr_with_scope()` first
- Fallback to `lower_condition_legacy()` helper if needed
- Added helper function `lower_condition_legacy()` (L379-413)
3. **contract.rs**: Already has `CondLoweringFailed` variant (L84)
### Files Modified (3 files)
- `src/mir/control_tree/normalized_shadow/common/expr_lowerer_box.rs` (+10 lines)
- `src/mir/control_tree/normalized_shadow/post_if_post_k.rs` (+44 lines, -25 lines legacy)
- `src/mir/control_tree/normalized_shadow/anf/contract.rs` (no change, already has variant)
### Files Created (4 files)
- `apps/tests/phase146_p0_if_cond_unified_min.hako` (exit code 7)
- `tools/smokes/.../phase146_p0_if_cond_unified_vm.sh`
- `tools/smokes/.../phase146_p0_if_cond_unified_llvm_exe.sh`
- `docs/development/current/main/phases/phase-146/README.md` (this file)
### Acceptance Criteria (P0)
- [x] Scope check added to ANF routing
- [x] Legacy inline lowering removed from post_if_post_k.rs
- [x] SSOT unified (lower_expr_with_scope is only entry point)
- [ ] Build passes (cargo build --release)
- [ ] Tests pass (cargo test --release --lib)
- [ ] Phase 145 regression: 0 failures
- [ ] Fixture exit code: 7 (VM + LLVM EXE)
## Phase 146 P1: 条件式 ANF 有効化planned
**Goal**: Enable ANF in conditions for `PureOnly` scope behind a dev flag, starting with whitelisted intrinsic (`String.length()`).
### Planned Implementation
1. **expr_lowerer_box.rs**: Allow ANF for PureOnly with env flag
2. **anf/execute_box.rs**: Add Compare operator support
3. **config/env/joinir_dev.rs**: Add `anf_allow_pure_enabled()` function
## Phase 147 P0: 複合条件の順序固定planned
**Goal**: Extend recursive ANF to Compare operators for compound conditions.
**Status**: Not yet implemented
### Planned Implementation
1. **anf/plan_box.rs**: Add Compare case to plan_expr()
## Testing
### P0 Smoke Tests
```bash
# VM
./tools/smokes/v2/profiles/integration/apps/phase146_p0_if_cond_unified_vm.sh
# Expected: exit 7
# LLVM EXE
./tools/smokes/v2/profiles/integration/apps/phase146_p0_if_cond_unified_llvm_exe.sh
# Expected: exit 7
```
### Regression Tests
Phase 145 smokes must still pass:
- `phase145_p1_anf_length_min` → exit 12
- `phase145_p2_compound_expr_binop_min` → exit 18
- `phase145_p2_compound_expr_double_intrinsic_min` → exit 5
