fix(packaging): ship packages@unom.io as the maintainer, not noreply@anthropic.com

Every Linux package declared its maintainer as `noreply@anthropic.com` — the
git co-author trailer address, copied out of commit metadata into PACKAGE
metadata, where it is user-visible:

  * deb:   `Maintainer:` in the host/client/web/scripting control files, plus
           the generated debian/changelog trailer  (`dpkg -s punktfunk`)
  * rpm:   all three %changelog entries                (`rpm -q --changelog`)
  * arch:  the PKGBUILD Maintainer comment

So installed packages named Anthropic as the maintainer of this project, and
pointed anyone with a packaging problem at an address that discards mail.

packages@unom.io is the project's real packaging identity — it's already the
EdDSA key (AF245C506F4E4763, "punktfunk packages") that sign-rpms.sh signs
every RPM with, and it's what packaging/rpm/README and the bootc Containerfile
document. The RPMs were therefore SIGNED by packages@unom.io while DECLARING
noreply@anthropic.com; those now agree.

Checked the other publisher surfaces — the Inno installer (AppPublisher=unom),
the flatpak metainfo (developer id io.unom) and the decky package.json were
already correct.
