god added a `correctDob` (DD.MM.YYYY) decisions field: the matched (name+dob)
record is a DUPLICATE with a wrong birthdate → remap its DOB to correctDob so
dedup MERGES it into the canonical same-named animal. apply_dob_remaps runs
BEFORE dedup (it changes the dedup identity); tolerates a missing file; logged
as "DOB-Remaps: N". First use: Chelsea *15.10.2021 → *02.04.2021 (merges into
the canonical record). test_extract covers the remap + that both records then
share one name+dob identity.
Extractor-only. python + dotnet 121/121 green.
