finalOutput now recovers the front-loaded answer when the terminal turn is a
sources/citations-only addendum ("Sources: [x](url), ..."), not just when it is
empty or a back-reference. It recovers the prior substantive answer and appends
the (real) citations below it. Guards: citation-DOMINANCE (a prose answer that
merely opens with "Source: ... http://..." is left as the answer), ^-anchored
heading, citations recovery decoupled from the terminal-length ratio (concise
answers recover too), preamble filter applied only in the borderline band
(long answers opening with "Sure,"/"Let me" are not vetoed), and a dedup that
ignores <url> angle-bracket wrappers. Healthy terminal answers unchanged; zero
extra model calls.
Fixes mort #1418. Gadfly-reviewed (6 reviewers) + adversarially pre-verified;
all findings graded, real ones addressed.
