cleanup: remove redundant save in abortTask

Removes the final `modifyClineMessages` call from `abortTask`.

This operation was redundant because all `clineMessages` mutations are already wrapped in atomic transactions, ensuring the on-disk state is always synchronized. This change simplifies the abort logic and avoids a superfluous file write.
