Unit: parse -y/--fuzzy and --no-fuzzy negation (order-independent), -W and
--no-delta leave fuzzy inert, --fuzzy implies --incremental/--delta, and
validate_config rejects fuzzy with -s (chunk serialization) and -f
(sendfile). Config: fuzzy survives the socketpair wire round-trip.
Integration (TestFuzzy, byte counts via a new CountingProxy helper): the
rename case transfers a 2 MiB file in a few percent of its size with byte-
exact output under --fuzzy, while the no-fuzzy, no-candidate, dissimilar-
sibling and --whole-file runs send the whole file; -y alias; -m parity;
dest-holds-unsuitable-file falls back to the sibling; --delay-updates and
--remove-source-files keep their semantics on fuzzy transfers.
