Cloud Contacts: All-in-One

This update improves the sync engine's reliability and network performance, resolving connection issues with iCloud and Microsoft accounts while introducing guided setup links for smoother provider configuration. • **iCloud Sync Fix**: Resolves a URL formatting bug where contact download paths from iCloud would occasionally become malformed, ensuring all cloud contacts sync completely and without error. • **Robust Sync Engine**: Fixed a task concurrency issue in the synchronization coordinator that could cause multi-account syncs to freeze or time out under certain network loads. • **Guided iCloud Setup**: Added a direct link to the web setup guide when configuring an iCloud account, making it simple to set up app-specific passwords. • **Connectivity Stability**: Strengthened request timeouts and error-handling logic for Microsoft Contacts and general CardDAV endpoints to prevent hangs in poor network conditions.
