WSL2環境Claude Code の入力待ちを Windows トースト通知で気付けるようにする (BurntToast + hook)

# NuGet provider を先にインストール (これがないと BurntToast のインストールで止まる)
powershell.exe -NoProfile -Command "Install-PackageProvider -Name NuGet -Scope CurrentUser -Force"

# BurntToast 本体をインストール
powershell.exe -NoProfile -Command "Install-Module -Name BurntToast -Scope CurrentUser -Force"

powershell.exe -NoProfile -ExecutionPolicy Bypass -Command "New-BurntToastNotification -Text 'Claude Code', '入力待ちです'"

#!/bin/bash
# Claude Code Notification hook: WSL2 → Windows トースト通知 + 完了音

# 使い方:
#   bash notify-claude-input.sh [MESSAGE [DELAY_SEC]]   # 通知発火 (即時 or 遅延 ARM)
#   bash notify-claude-input.sh --clear                  # 自セッションのマーカーをクリア
