Update snapshot files and enhance VFS event handling

- Updated snapshot files to reflect changes in IDs for consistency across connected mode tests.
- Improved VFS event processing in ChangeProcessor to handle multiple events more efficiently, ensuring consistent message structure across platforms.
- Added merging functionality for patch sets to consolidate changes from various VFS events, enhancing synchronization reliability.

These changes improve the accuracy of test snapshots and optimize VFS event management.
