Preserve hard links: source files sharing (st_dev,st_ino) are recreated as hard links on the destination; only the first member's data crosses the wire (siblings ride a payload-less STATUS_HARDLINK frame). Ordering requires the single-FIFO-writer receiver + forced sequential scan (documented). On link() failure falls back to a byte-identical local copy. Rejects -s and --append. PROTOCOL_VERSION 2.11.0 -> 2.12.0. Verified: STRICT_WARNINGS build clean, unit 28/28, 6 new integration tests (8 incl. --existing asymmetric), 298 full passed / 12 skipped / 1 xpassed. Independent c-review REQUEST CHANGES; fixes applied: deleted the dead HardLinkRegistry (ordering holds by FIFO writer), and --existing no longer aborts when the first member is absent but the sibling exists.
