refactor(actor): implement replica sync and ref update notification system

Browse Source 
- Add is_write parameter to remote clients for read/write routing distinction
- Introduce RepoEntry struct with role tracking (primary/replica) for repositories
- Replace HashSet with HashMap for repository storage with role metadata
- Add ROLE_PRIMARY and ROLE_REPLICA constants for node role identification
- Implement FindPrimary and FindReplica RPC methods for role-based routing
- Add RefUpdateEvent message type for propagating reference updates
- Create sync module with BundleApplicator for handling replica synchronization
- Implement notify_ref_update calls after branch/tag/commit operations
- Add broadcast_ref_update function to propagate events across cluster nodes
- Modify route_repository to prioritize primary for writes and replicas for reads
- Update actor message handling to support role-based repository discovery
- Implement sync_from_primary function using pack protocol for incremental updates
