kazuki e799c35efd refactor: migrate to clean architecture with src/ layout
## Migration Summary
- Moved from flat `superclaude/` to `src/superclaude/` (PEP 517/518)
- Deleted old structure (119 files removed)
- Added new structure with clean architecture layers

## Project Structure Changes
- OLD: `superclaude/{agents,commands,modes,framework}/`
- NEW: `src/superclaude/{cli,execution,pm_agent}/`

## Build System Updates
- Switched: setuptools → hatchling (modern, PEP 517)
- Updated: pyproject.toml with proper entry points
- Added: pytest plugin auto-discovery
- Version: 4.1.6 → 0.4.0 (clean slate)

## Makefile Enhancements
- Removed: `superclaude install` calls (deprecated)
- Added: `make verify` - Phase 1 installation verification
- Added: `make test-plugin` - pytest plugin loading test
- Added: `make doctor` - health check command

## Documentation Added
- docs/architecture/ - 7 architecture docs
- docs/research/python_src_layout_research_20251021.md
- docs/PR_STRATEGY.md

## Migration Phases
- Phase 1: Core installation  (this commit)
- Phase 2: Lazy loading + Skills system (next)
- Phase 3: PM Agent meta-layer (future)

# Context Window Analysis: Old vs New Architecture
**Date**: 2025-10-21
**Related Issue**: [#437 - Extreme Context Window Optimization](https://github.com/SuperClaude-Org/SuperClaude_Framework/issues/437)
**Status**: Analysis Complete
---
## 🎯 Background: Issue #437
**Problem**: SuperClaude消費 55-60% のcontext window
- MCP tools: ~30%
- Memory files: ~30%
- System prompts/agents: ~10%
- **User workspace: たった30%**
**Resolution (PR #449)**:
- AIRIS MCP Gateway導入 → MCP消費 30-60% → 5%
- **結果**: 55K tokens → 95K tokens利用可能40%改善)

## 📊 今回のクリーンアーキテクチャでの改善
### Before: カスタムインストーラー型Upstream Master
**インストール時の読み込み**:
```

└── modes/ # 全モード
├── MODE_Brainstorming.md
├── MODE_Business_Panel.md
├── ... (7 files)
Total: ~210KB (推定 50K-60K tokens)
```
**問題点**:
1. ❌ 全ファイルが `~/.claude/` に展開
2. ❌ Claude Codeが起動時にすべて読み込む
3. ❌ 使わない機能も常にメモリ消費
4. ❌ Skills/Commands/Modesすべて強制ロード
### After: Pytest Plugin型This PR
**インストール時の読み込み**:
```
site-packages/superclaude/
├── __init__.py # Package metadata (~0.5KB)
├── pytest_plugin.py # Plugin entry point (~6KB)
├── pm_agent/ # PM Agentコアのみ
│ ├── __init__.py
│ ├── confidence.py # ~8KB
│ ├── self_check.py # ~15KB
│ ├── reflexion.py # ~12KB

├── main.py # ~3KB
├── doctor.py # ~4KB
└── install_skill.py # ~3KB
Total: ~88KB (推定 20K-25K tokens)
```
**改善点**:
1. ✅ 必要最小限のコアのみインストール
2. ✅ Skillsはオプションユーザーが明示的にインストール
3. ✅ Commands/Modesは含まれないSkills化
4. ✅ pytest起動時のみplugin読み込み

## 🔢 トークン消費比較
### シナリオ1: Claude Code起動時
**Before (Upstream)**:
```
MCP tools (AIRIS Gateway後): 5K tokens (PR #449で改善済み)
Memory files (~/.claude/): 50K tokens (全ドキュメント読み込み)
SuperClaude components: 10K tokens (Component/Installer)
─────────────────────────────────────────
Total consumed: 65K tokens
Available for user: 135K tokens (65%)
```
**After (This PR)**:
```
MCP tools (AIRIS Gateway): 5K tokens (同じ)
Memory files (~/.claude/): 0K tokens (何もインストールしない)
SuperClaude pytest plugin: 20K tokens (pytest起動時のみ)
─────────────────────────────────────────
Total consumed (session start): 5K tokens
Available for user: 195K tokens (97%)
※ pytest実行時: +20K tokens (テスト時のみ)
```
**改善**: **60K tokens削減 → 30%のcontext window回復**

│ ├── token-counter.md # ~8KB = 2K tokens
│ └── pm-formatter.md # ~10KB = 2.5K tokens
└── 関連ドキュメント # ~20KB = 5K tokens
─────────────────────────────────────────
Total: ~17K tokens
```
**After (This PR)**:
```
PM Agentコアのみインポート:
├── confidence.py # ~8KB = 2K tokens
├── self_check.py # ~15KB = 3.5K tokens
├── reflexion.py # ~12KB = 3K tokens
└── token_budget.py # ~10KB = 2.5K tokens
─────────────────────────────────────────
Total: ~11K tokens
```
**改善**: **6K tokens削減 (35%削減)**
---
### シナリオ3: Skills使用時オプション

```
全Skills強制インストール: 50K tokens
```
**After (This PR)**:
```
デフォルト: 0K tokens
ユーザーが install-skill実行後: 使った分だけ
```
**改善**: **50K tokens削減 → オプトイン方式**

## 🎯 機能喪失リスクの検証
### ✅ 維持される機能
1. **PM Agent Core**:
- ✅ Confidence checking (pre-execution)
- ✅ Self-check protocol (post-implementation)
- ✅ Reflexion pattern (error learning)
- ✅ Token budget management
2. **Pytest Integration**:
- ✅ Pytest fixtures auto-loaded
- ✅ Custom markers (`@pytest.mark.confidence_check`)
- ✅ Pytest hooks (configure, runtest_setup, etc.)
3. **CLI Commands**:
-`superclaude doctor` (health check)
-`superclaude install-skill` (Skills installation)
-`superclaude --version`
### ⚠️ 変更される機能
1. **Skills System**:
- ❌ Before: 自動インストール
- ✅ After: オプトイン(`superclaude install-skill pm`
2. **Commands/Modes**:
- ❌ Before: 自動展開
- ✅ After: Skills経由でインストール
3. **Framework Docs**:
- ❌ Before: `~/.claude/superclaude/framework/`
- ✅ After: PyPI package documentation
### ❌ 削除される機能
**なし** - すべて代替手段あり:
- Component/Installer → pytest plugin + CLI
- カスタム展開 → standard package install

## 💡 追加改善提案
### 1. Lazy Loading (Phase 3以降)
**現在**:
```python
# pytest起動時に全モジュールimport
from superclaude.pm_agent import confidence, self_check, reflexion, token_budget
```
**提案**:
```python
# 使用時のみimport
def confidence_checker():
from superclaude.pm_agent.confidence import ConfidenceChecker
return ConfidenceChecker()
```
**効果**: pytest起動時 20K → 5K tokens (15K削減)
### 2. Dynamic Skill Loading
**現在**:
```bash
# 事前にインストール必要
superclaude install-skill pm-agent
```
**提案**:
```python
# 使用時に自動ダウンロード & キャッシュ
@pytest.mark.usefixtures("pm_agent_skill") # 自動fetch
def test_example():
...
```
**効果**: Skills on-demand、ストレージ節約
