* feat: --skip-hardlinks flag Adds a --skip-hardlinks flag that will not process any files that have an active hardlink. Without a pre-scan to identify hardlink targets and relink them after copies, all this would result in is duplication. You'd then have to run another de-duplicator, which doesn't have knowledge of the balancing, and could arbitrarily undo the balancing work. * doc: .rebalance suffix -> .balance suffix * doc: add --skip-hardlinks parameter to README * test: add unit tests for --skip-hardlink
