Selfhosting Dev d90216e9c4 📚 Phase 15 - セルフホスティング戦略の明確化とEXE-first実装

## 主な変更点

### 🎯 戦略の転換と明確化
- PyVMを開発ツールとして位置づけ（本番経路ではない）
- EXE-first戦略を明確に優先（build_compiler_exe.sh実装済み）
- Phase順序の整理: 15.2(LLVM)→15.3(コンパイラ)→15.4(VM)

### 🚀 セルフホスティング基盤の実装
- apps/selfhost-compiler/にNyashコンパイラMVP実装
  - compiler.nyash: メインエントリー（位置引数対応）
  - boxes/: parser_box, emitter_box, debug_box分離
- tools/build_compiler_exe.sh: ネイティブEXEビルド＋dist配布
- Python MVPパーサーStage-2完成（local/if/loop/call/method/new）

### 📝 ドキュメント整備
- Phase 15 README/ROADMAP更新（Self-Hosting優先明記）
- docs/guides/exe-first-wsl.md: WSLクイックスタート追加
- docs/private/papers/: 論文G～L、爆速事件簿41事例収録

### 🔧 技術的改善
- JSON v0 Bridge: If/Loop PHI生成実装（ChatGPT協力）
- PyVM/llvmliteパリティ検証スイート追加
- using/namespace機能（gated実装、Phase 15では非解決）

## 次のステップ
1. パーサー無限ループ修正（未実装関数の実装）
2. EXEビルドとセルフホスティング実証
3. c0→c1→c1'ブートストラップループ確立

Nyash Style Guide (Phase 15)

Goals

Keep Nyash sources readable and structured. Favor simple, predictable formatting compatible with reversible formatting (nyfmt PoC).

Formatting

Indent with 2 spaces (no tabs).
Braces: K&R style (opening brace on the same line).
Max line length: 100 characters (soft limit).
One statement per line. Use semicolons only when placing multiple statements on one physical line.
Blank lines: separate top‑level box declarations with one blank line; no trailing blank lines at file end.

Statements and ASI

Newline is the primary separator. See reference/language/statements.md.
Do not insert semicolons before else.
When breaking expressions across lines, break after an operator or keep the expression grouped.

using / include

Place all using lines at the top of the file, before code.
One using per line; no trailing semicolons.
Sort using targets alphabetically; group namespaces before file paths.
Prefer as aliases for readability. Aliases should be PascalCase.
Keep include adjacent to using group, sorted and one per line.

Naming (conventions for Nyash code)

Boxes (types): PascalCase (e.g., ConsoleBox, PathBox).
Methods/functions: lowerCamelCase (e.g., length, substring, lastIndexOf).
Local variables: concise lowerCamelCase (e.g., i, sum, filePath).
Constants (if any): UPPER_SNAKE_CASE.

Structure

Top‑to‑bottom: using/include → static/box declarations → helpers → main.
Keep methods short and focused; prefer extracting helpers to maintain clarity.
Prefer pure helpers where possible; isolate I/O in specific methods.

Examples

using core.std as Std
using "apps/examples/string_p0.nyash" as Strings

static box Main {
  escJson(s) {  // lowerCamelCase for methods
    local out = ""
    local i = 0
    local n = s.length()
    loop(i < n) {
      local ch = s.substring(i, i+1)
      if ch == "\\" { out = out + "\\\\" }
      else if ch == "\"" { out = out + "\\\"" }
      else { out = out + ch }
      i = i + 1
    }
    return out
  }

  main(args) {
    local console = new ConsoleBox()
    console.println("ok")
    return 0
  }
}

CI/Tooling

Optional formatter PoC: see docs/tools/nyfmt/NYFMT_POC_ROADMAP.md.
Keep smoke scripts small and fast; place them under tools/.
