feat(void): add xbps template for the voculinux app

Ticket xavierk/voculinux#27, built on #18 (rename) plus the #25/#26
dependency templates. The template builds the app from the canonical
checksum-verified release sdist, depends on Void's interpreter, GTK,
desktop bindings and packaged Python libraries, and installs the
renamed desktop entry, icons and a packaged-install marker. No speech
models, no vendored wheels, no pip at build or install time.

Packaged installs keep background update checks as a signal, but every
update affordance presents the package-manager path
(src/vocalinux/utils/packaging.py). Also corrects the Void distro
inventory (Ayatana provider name; ydotool marked absent) and regens
the installer map.
