The 2.0.0 release commit assembled every fragment into CHANGELOG.md's
[2.0.0] section and deleted them - except this one, which landed on main
in the delayed-send discard fix after the release branch was cut, and
whose deletion was planned as a rebase that the merge order skipped. Its
entry is already in the released [2.0.0] section, so the file is purely
leftover; removing it keeps the next release's assembly from reporting
the change twice.
