Pull Request Overview

This PR introduces queueing and fan-out support for Syncerbell, allowing sync operations to be distributed across multiple workers or processes. It also includes several improvements to the sync system architecture and API design.

• Adds ISyncQueueService and SyncQueueService for creating queued sync entries for distributed processing
• Introduces AcquireLeaseBehavior enum to control lease acquisition behavior during sync operations
• Refactors sync log persistence interfaces to support finding entries by ID and improved lease management

• [nitpick] The method name 'TryProcessExistingEntry' is ambiguous. Consider renaming to 'CanAcquireEntry' or 'ValidateEntryForAcquisition' to better reflect its purpose of checking if an entry can be acquired.
