nyash-codex ef71ea955c feat(control_tree): Phase 133 P0 - Multiple post-loop assigns support

Extend Phase 132's loop(true) + post-loop to accept multiple assignments:

Goal: `x=0; loop(true){ x=1; break }; x=x+2; x=x+3; return x` → exit code 6

Implementation:
- Extended loop_true_break_once.rs pattern detection (len() == 2 → len() >= 2)
- Added iterative assignment lowering (for loop over post_nodes)
- Reused Phase 130's lower_assign_stmt for each assignment
- Maintained ExitMeta DirectValue mode (PHI-free)

Changes:
- apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase133_*_multi_add_*.sh (new smokes)
- src/mir/control_tree/normalized_shadow/loop_true_break_once.rs (+30 lines)
- docs/development/current/main/phases/phase-133/README.md (new documentation)
- docs/development/current/main/10-Now.md (Phase 133 entry added)

Scope (Phase 130 baseline):
- ✅ x = <int literal>
- ✅ x = y (variable copy)
- ✅ x = x + <int literal> (increment)
- ❌ Function calls / general expressions (future phases)

Design principles:
- Minimal change: ~30 lines added
- SSOT preservation: env_post_k remains single source of truth
- Reuse: Leveraged existing lower_assign_stmt
- Fail-Fast: Contract violations trigger freeze_with_hint

Test results:
- cargo test --lib: 1176 PASS
- Phase 133 VM: PASS (exit code 6)
- Phase 133 LLVM EXE: PASS (exit code 6)
- Phase 132 regression: PASS (exit code 3)
- Phase 131 regression: PASS (exit code 1)
- Phase 97 regression: PASS

Architecture maintained:
- 5-function structure unchanged (main/loop_step/loop_body/k_exit/post_k)
- PHI-free DirectValue mode
- Zero changes to ExitMeta, merge logic, or JoinIR contracts

Hakorune Smoke Tests v2 — Guide (Nyash-compatible)

Overview

Entry: tools/smokes/v2/run.sh — unified runner for quick/integration/full.
Profiles:
- quick — fast developer checks.
- integration — VM↔LLVM parity, basic stability.
- full — comprehensive matrix.

🎯 Two Baselines (Runbook)

これから開発の基準となる2つのベースライン：

📦 VM ライン（Rust VM - 既定）

用途: 開発・デバッグ・検証用（高速・型安全）

# ビルド
cargo build --release

# 一括スモークテスト
tools/smokes/v2/run.sh --profile quick

# 個別スモークテスト
tools/smokes/v2/run.sh --profile quick --filter "<glob>"
# 例: --filter "core/json_query_min_vm.sh"

# 単発実行（参考）
$NYASH_BIN --backend vm apps/APP/main.hako

⚡ llvmlite ライン（LLVMハーネス）

用途: 本番・最適化・配布用（実証済み安定性）

前提: Python3 + llvmlite

pip install llvmlite  # 未導入の場合

実行手順:

# ビルド（LLVM_SYS_180_PREFIX不要！）
cargo build --release --features llvm

# 一括スモークテスト
tools/smokes/v2/run.sh --profile integration

# 個別スモークテスト
tools/smokes/v2/run.sh --profile integration --filter "<glob>"

# 単発実行
NYASH_LLVM_USE_HARNESS=1 $NYASH_BIN --backend llvm apps/tests/peek_expr_block.hako

# 有効化確認
$NYASH_BIN --version | rg -i 'features.*llvm'

💡 重要: 両方のラインのテストが通ることで、MIR14統一アーキテクチャの品質を保証！

🔁 QuickでAST/LLVM系も実行したいとき

通常、quick は LLVM未ビルド時に AST/LLVM系テストを自動で SKIP します。 Quickでも実行したい場合は、先に LLVM 有効でビルドしてください：

LLVM_SYS_180_PREFIX=$(llvm-config-18 --prefix) cargo build --release --features llvm
tools/smokes/v2/run.sh --profile quick

テストランナーは LLVM 非対応時にヒントを出力します（buildコマンドの案内）。

Notes

Using resolution: prefer nyash.toml aliases (SSOT). Some tests may enable NYASH_ALLOW_USING_FILE=1 internally for convenience.
Plugin warnings are informational; smokes are designed to pass without dynamic plugins.
Harness single-run may take longer due to link+exec; integration profile includes generous timeouts.
Binary selection in scripts: always use $NYASH_BIN (the runner sets it to target/release/hakorune when present, otherwise falls back to nyash).
Branding: user‑visible messages prefer “Hakorune”; the legacy nyash binary remains for compatibility but may be gated（HAKO_ALLOW_NYASH=1）。

Dev Mode (defaults)

In v2 smokes, the quick profile exports NYASH_DEV=1 by default.
- This enables CLI --dev-equivalent defaults inside Nyash:
  - AST using ON (SSOT + AST prelude merge)
  - Operator Boxes in observe mode (no adoption)
  - Minimal diagnostics; output parity is preserved
You can also run manually with nyash --dev script.hako.

Common commands

Quick suite (auto NYASH_DEV=1):
- tools/smokes/v2/run.sh --profile quick
Focus JSON smokes:
- tools/opbox-json.sh (Roundtrip/Nested, plugins disabled, generous timeout)
One-off program (VM):
- $NYASH_BIN --backend vm --dev apps/APP/main.hako

Key env knobs

NYASH_DEV=1 — enable dev defaults (same effect as --dev).
SMOKES_DEFAULT_TIMEOUT — per test timeout seconds (default 15 for quick).
SMOKES_PLUGIN_MODE=dynamic|static — plugin mode for preflight (auto by default).
SMOKES_FORCE_CONFIG=rust_vm_dynamic|llvm_static — force backend config.
SMOKES_NOTIFY_TAIL — lines to show on failure tail (default 80).
