[hotfix] Remove unused DurableExecutionManager.maybePruneState helper#682

Conversation
`DurableExecutionManager.maybePruneState(Object, long)` has no production callers and is not part of the `ActionStatePersister` interface — only a single test method references it. It is a leftover from the apache#546 refactor. Timeline (from `git log -S "maybePruneState"`): - apache#138 introduced `maybePruneState(...)` as a `private` helper on `ActionExecutionOperator`, called from the per-key completion path: `maybePruneState(key, sequenceNumber);`. - apache#603 ("Fix prune state corner cases around checkpoints") deliberately removed both the call site and the helper. The fix moved pruning from the per-key path to the checkpoint-driven path inside `notifyCheckpointComplete`, where it now prunes using `lastCompletedSequenceNumber` captured at the checkpoint barrier via `snapshotLastCompletedSequenceNumbers`. That is the current/correct architecture. - apache#546 ("Refactor ActionExecutionOperator into focused manager classes") extracted `DurableExecutionManager` and re-surfaced `maybePruneState(...)` on the new class — but no caller was re-added, correctly so. This commit removes the orphan. Changes: - Delete `DurableExecutionManager.maybePruneState(Object, long)`. - Drop the `dem.maybePruneState("k", 0L);` line from the existing `noStoreModeMakesAllMaybeOperationsNoOp` no-op coverage test. The remaining `maybe*` no-op assertions still cover the null-store invariant for every `maybe*` method on the class today.
