> When lifecycle expiration is configured to move expired keys to trash,
> {{KeyLifecycleService}} currently clears the pending key list even if
> {{moveToTrash}} fails. It can then save lifecycle scan state past those keys,
> so the failed keys are not retried until a later full scan.
> We should avoid marking failed trash moves as processed. If moving expired
> keys or directories to trash fails, the lifecycle task should fail for that
> bucket without saving scan state past the failed entries. The next lifecycle
> run can then retry them from the previous scan position.
> h2. Benefits
> * Preserves trash semantics: keys are not directly deleted when trash move
> fails.
> * Prevents lifecycle from silently skipping expired keys.
> * Retries failed keys sooner, instead of waiting for a full bucket scan to
> complete.
> * Keeps scan state accurate: only successfully handled entries are marked as
> progress.
