Andy Dixon 6ac02cdda5 packaging: publish nexusterminal to repo.dixon.cx and Homebrew; install instructions 
- packaging/repo.sh: download release assets over HTTPS (no GitHub API),
  show nfpm errors, PKGREL for packaging-only revisions, and declare ALSA
  as a hard dependency (the release binary links libasound.so.2), with
  libasound2t64 preferred so Ubuntu 24.04 doesn't pick the OSS shim.
  Verified by clean installs on Debian 12/13, Ubuntu 22.04/24.04,
  Fedora 42 and Arch.
- README: Install section (Homebrew cask, apt, dnf/zypper, pacman, zips).

# Publish a Nexus Terminal release as the `nexusterminal` package (.deb, .rpm and Arch) in the
# signed apt, dnf and pacman repositories served at https://repo.dixon.cx.
#
# packaging/repo.sh # the newest tag
# packaging/repo.sh v3.0.2 # a given tag
#
# Unlike the command-line tools' copies of this script, nothing is built here: Nexus is a GUI app
# linked against the platform's windowing stack, so the packages wrap the official binaries that
# the Release Builds workflow made for the tag (native glibc builds on amd64 and arm64). They're
# downloaded from the GitHub release and checked against its SHA256SUMS first.
#
# The publish half is the same as in ../../../mapsize/packaging/repo.sh and friends: every index
# is rebuilt over all packages in the repository, so other projects' packages are kept.
#
# Needs: curl, unzip, curl (for the pinned nfpm), docker, gpg, apt-ftparchive, flock.
# REPO_DIR where the repository lives (default below)
# REPO_GNUPGHOME GnuPG home holding the signing key (default below)
# ARCHS package architectures (default: amd64 arm64)

# The binaries come from ubuntu-22.04 runners: glibc 2.35. Windowing, GL and audio libraries are
# loaded at run time, so they're recommended rather than hard dependencies (any desktop has them).
# ALSA is linked directly (RDP audio), so it's a hard dependency. libasound2t64 comes first: on
# Ubuntu 24.04 and later plain libasound2 is only a virtual name, which apt may satisfy with the
# OSS shim liboss4-salsa-asound2 (missing real ALSA symbols); older Debian falls through to it.
