### Summary This patch preserves the candidate `votedKey` when transitioning to `LeaderState`. Before this change, `LeaderState.election()` always returned an elected-leader `ElectionState` with an empty `votedKey`. Since `QuorumState.transitionToLeader` writes the new state's election state to the quorum state store, the candidate's self-vote could be dropped during the candidate-to-leader transition. The patch passes the candidate election state's `votedKey` into `LeaderState` and keeps the same value across the soft `ResignedState` representation. This keeps the in-memory and persisted election-state representation consistent after a candidate becomes leader and later resigns. ### Testing ```bash ./gradlew :raft:unitTest -- This is an automated message from the Apache Git Service.
