This pull request fixes recovery in 3 scenarios:
All these scenarios are caused by unreplicated transactions from an old primary that has lost its primary status and is reconnecting as a replica. Different scenarios are caused by the number of unreplicated transactions and the number of new transactions on the new primary. LiteFS currently only supports asynchronous replication so unreplicated transactions will be lost in the event of a primary change.
