- 2026-07-09 is a Thursday; fix the weekday in the rpm, debian, and
openSUSE 4.2.0 changelog entries (was "Wed").
- packaging/rpm/vaptvupt.spec: drop the stale vendored-library install
and %files entries (the libraries were removed in 4.1.0's source-only
switch), build with WITH_SDK=0, and list the actual vaptvupt binary
and shell completions. Mirrors the already-source-only openSUSE spec.
