Add cross-platform cookie extraction for Windows Chromium browsers: - Platform-aware path resolution (LOCALAPPDATA + windowsDataDir) - DPAPI key extraction via PowerShell for v10 cookies - AES-256-GCM decryption (Windows) alongside existing AES-128-CBC (macOS) - Multi-profile detection (Default + Profile N directories) - Network/Cookies path support for newer Chromium - SQLITE_CANTOPEN handling for Windows exclusive file locks - Informative v20 App-Bound Encryption error message - Short buffer protection in decryptWindows - Dangling timeout fix in DPAPI PowerShell call - 5 new AES-256-GCM round-trip and tamper-detection tests
When Windows v20 App-Bound Encryption prevents direct decryption: - New /cookie-picker/import-raw POST endpoint accepts pre-decrypted cookies - Picker UI shows console-script fallback with copy button - Script captures document.cookie and sends to gstack's import-raw endpoint - Domain validation skips cookies without a domain
- Windows: cmd /c start '' <url> (with empty title arg) - macOS: open <url>
