TapTap	e16db56580	feat: add delta transfer for incremental sync ... Implement rsync-style delta transfer using rolling checksums (Adler-32 + xxHash32). When a file exists on both sides but has changed, only the changed blocks are transmitted instead of the entire file. - New status codes: STATUS_DELTA_SIGNATURE, STATUS_DELTA_DATA - Protocol version bumped to 1.2.0 - Server generates block signature, client computes delta - Auto-fallback to whole-file when delta >= 70% of file size - Works with zstd compression on delta stream - Configurable block size (default 8KB, --delta-block flag) - 13 unit tests covering hashing, signature roundtrip, delta compute/apply, file growth/shrink, and decision logic	2026-07-18 20:00:15 +02:00
