Restructure the vmsync package to separate concerns and prepare for future dynamic state sync support. - Extract `finalizer.go` - VM state finalization logic (`finishSync`, `commitMarkers`) moved to dedicated `finalizer` struct. - Add `SyncStrategy` interface with `Start` method for sync execution. - Implement `staticStrategy` for current sequential sync behavior. - Simplify `client.go` to orchestrate sync lifecycle via strategy. This refactoring enables adding dynamic state sync as a separate strategy implementation without modifying existing static sync logic. resolves #4651 Signed-off-by: Tsvetan Dimitrov (tsvetan.dimitrov@avalabs.org)
