nyash-codex 0bba67a72c fix(parser): ParserBox.parse_program2 無限ループ回避 - PHI依存排除版 
## 問題
- Stage-1 CLI emit_program_json で無限ループ発生
- 初期ホワイトスペーススキップループで ws_cont_init PHIバグ
- ループ条件変数への代入が Header PHI に反映されず

## 根本原因
- Header PHI generation failure
- ws_cont_init = 0 実行後もループ条件で ws_cont_init == 1 が true

## 解決策
- PHI依存を完全排除：loop(ws_cont_init == 1) → loop(i < n)
- 条件付き break だけで制御（continue/break のみ）
- Header PHI に依存しない構造に書き換え

## 変更内容
- lang/src/compiler/parser/parser_box.hako:294-312
  - loop(ws_cont_init == 1) → loop(i < n) に変更
  - if whitespace { i++; continue } else { break }
  - ws_cont_init 変数を完全削除

## Phase 26-H 準備
- この修正により Stage-1 CLI が動作可能に
- JoinIR 実装の前提条件クリア
- PHI問題の暫定回避（根治は JoinIR で行う）

Hakorune Lang Line — Rust-less Kernel (C ABI)

Scope

  • This lang/ tree hosts the script-driven C ABI kernel artifacts for Phase 20.9+.
  • Goal: keep the runtime data plane callable without Rust on the hot path (Hakorune → LLVM → C ABI).

Principles

  • Separation: do not mix Rust crates or cargo-specific layout under this tree.
  • Ownership & ABI:
    • Any char* returned across the ABI is owned by the callee and must be freed via hako_mem_free().
    • Do not mix CRT free() across boundaries.
  • Fail‑Fast: no silent fallbacks. Missing symbols must be observable via short diagnostics.

Layout (initial)

  • c-abi/ — C shim(s) and headers for the minimal kernel surface
    • README.md — responsibilities, build notes, platform caveats
    • include/ — public headers (mirrored or thin wrappers)
    • shims/ — libc-backed shim(s) for canaries and local testing

Build & Link (dev)

  • C shim: build a shared library to satisfy symbols for the LLVM line canaries.
  • Link flags example:
    • Linux: -L$(pwd)/target/release -Wl,-rpath,$(pwd)/target/release -lhako_kernel_shim

Non‑Goals

  • Plugin loader, HostBridge router, Box/Type system — kept in Rust.

Selfhost Launcher (AOT)

Dev line (Stage1 core – experimental)

  • Dev build: tools/selfhost/build_stage1.sh → produces target/selfhost/hakorune
  • Role:
    • Fast iteration用の Stage1 selfhost バイナリ（Ny Executor / CLI 実験など）。
    • new CLI/runner 機能はまずこちらで開発・検証する。

Stable line (lang bin – snapshot)

  • Stable binary: lang/bin/hakorune
  • Build (pure-lang launcher, legacy bring-up):
    • lang/build/build_runner.sh → produces lang/bin/hakorune
    • Requirements: LLVM 18 dev (llvm-config-18)
  • Policy（Phase 25.1 以降の想定）:
    • target/selfhost/hakorune で十分に安定したら、その成果物を lang/bin/hakorune に昇格させる（手動コピー or 専用スクリプト）。
    • lang/bin/hakorune は「last known good」の Stage1 コア EXE として扱い、配布や外部からの参照時は原則こちらを基準にする。

Notes

  • lang/ 以下は「最終的に 1 つの Stage1 コア EXE（hakorune）を構成するソース群」という前提で整理する。
  • target/selfhost/hakorune は開発中の最新版、lang/bin/hakorune は安定版スナップショットという役割分担にする。
