+	 * Performs a hard reset of Electron and VS Code caches to fix corrupted runtime files.
+	 * This method clears all Electron cache directories, IndexedDB, Local Storage, Session Storage,
+	 * and other cached data that may become corrupted and persist even after normal resets.
+	 *
+	 * The operation targets platform-specific cache locations:
+	 * - macOS: ~/Library/Caches/com.microsoft.VSCode*, ~/Library/Application Support/Code/*
+	 * - Windows: %APPDATA%/Code/*, %LOCALAPPDATA%/Microsoft/vscode-cpptools
+	 * - Linux: ~/.cache/Code*, ~/.config/Code/*
+	 *
+	 * After clearing caches, it also performs a regular state reset and offers to restart VS Code.
+	 *
+	 * @returns {Promise<void>} Resolves when the cache clearing operation is complete
