feat: implement launch at startup functionality in zn-ai

- Added a new setting for "launch at startup" in the GeneralSettingsPanel.
- Integrated the setting with the existing settings store and IPC mechanisms.
- Implemented platform-specific logic for enabling/disabling startup behavior in the main process.
- Created a new service for managing launch at startup settings, including Linux desktop entry creation.
- Added unit tests for the new functionality and ensured existing tests are updated accordingly.
