The Decky plugin (b3f98a5) launches `punktfunk-client`, but the Arch package only
shipped the host, so the Deck had nothing to launch. Convert the PKGBUILD to a
split package (pkgbase=punktfunk → punktfunk-host + punktfunk-client), mirroring the
rpm subpackages and the two deb build scripts:
- punktfunk-host: unchanged artifact set + NVENC/compositor optdepends.
- punktfunk-client: the GTK4 binary + io.unom.Punktfunk.desktop + the hidraw udev
rule + the 32MB recv-buffer sysctl; depends gtk4/libadwaita/sdl3/ffmpeg/pipewire/
opus; optdepends libva-mesa-driver (VAAPI decode on the Deck's AMD APU, software
fallback otherwise). New punktfunk-client.install scriptlet.
- build-sysext.sh now derives the package name from the file, so it wraps either the
host OR the client into a systemd-sysext .raw — on a Deck you wrap the client.
- README: split-package usage + a "Steam Deck (the client)" section tying the sysext
to the Decky plugin (client is on PATH → plugin launches `punktfunk-client
--connect host:port`). Clarified the VAAPI gap is host-ENCODE only; the client
DECODES via VAAPI on the Deck today, so streaming to a Deck works now.

# Wrap a built punktfunk pacman package into a systemd-sysext image — the update-survivable way to
|
|
# add it to an immutable Arch-derived distro (SteamOS 3): the .raw overlays /usr read-only from the
|
|
# writable /var/lib/extensions/, so it persists across A/B OS updates with no `steamos-readonly
|
|
# disable`. Works for either split package — on a Steam Deck you'd wrap the CLIENT. Needs
