[Bug] File corruption when executing PowerShell backtick escaping from WSL Bash

Bug Description
報告内容の例

## バグ報告: WSL Bash から PowerShell 実行時のファイル破損

### 環境

• OS: Windows (WSL)
• Claude Code version:  2.0.72

### 再現手順

1. Bash から PowerShell コマンドでバッククォート置換を実行
2. コマンド: powershell -Command "... -replace '\\\', '`' ..."

### 期待される動作
バッククォートのエスケープが正しく処理される

### 実際の動作

• Bash がバッククォートをコマンド置換として解釈
• コマンドが部分的に実行され、ファイルが破損（各行先頭にバッククォートが追加）

### 提案

• 複雑なシェル間連携が必要な場合の警告
• または Edit ツールでのバッククォート処理の改善

Environment Info

• Platform: win32
• Terminal: windows-terminal
• Version: 2.0.72
• Feedback ID: 6f33a5d6-d006-4abb-8ad3-41e9bcb26018
