Adds the v26.14.0 row to the release table. This is the commit the v26.14.0 tag
will be pushed onto, matching how v26.13.0 was cut (#716).
Contents since v26.13.0: the #726 bitmap-subtitle -readrate starvation fix
(headline), the #674/#688 decisions-validator PyYAML cross-check, the
#706/#707/#711 review-verdict raced-sentinel fix, and two Renovate bumps.
Replaces the branch behind PR #738, which never received a pull_request CI run
across six trigger attempts (two pushes, a force-push after rebase, a
close/reopen, a body edit, and a spaced push on an idle queue). A
workflow_dispatch run did complete green but writes no commit statuses, so it
cannot satisfy the required checks. Opening a fresh PR produces an `opened`
event rather than a synchronize, which is a different path.
No [skip ci] token -- this branch's merge commit is the v26.14.0 tag target.
