/**
 * mcp/skills/repairOutlookDatabase.ts — repair_outlook_database skill
 *
 * Locates and prepares to run the Microsoft Outlook database repair utility.
 * On macOS, identifies the Outlook Database Utility or Profile Manager.
 * On Windows, locates scanpst.exe.
 * Use when Outlook crashes, hangs, or shows data corruption errors.
 *
 * Platform strategy
 * -----------------
 * darwin  Checks /Applications/Microsoft Outlook.app/Contents/SharedSupport/
 *         and ~/Library/Group Containers/UBF8T346G9.Office/ for profile data.
 * win32   Searches common scanpst.exe paths and PST/OST files via PowerShell.
 *
 * Smoke test
