scripts/punktfunk-host.service is dev-oriented — its ExecStart references the
source tree (%h/punktfunk/target/release/punktfunk-host). When the deb/rpm ship
it to /usr/lib/systemd/user, a fresh install with no hand-rolled unit would try
to run a binary that isn't there. Rewrite the ExecStart to the installed
/usr/bin/punktfunk-host during packaging (sed in build-deb.sh + the spec); the
source unit stays as-is for from-source dev. Hosts with a custom ~/.config unit
(which shadows the packaged one) are unaffected.

Hook the Linux client into the existing packaging CI:
- deb.yml builds both binaries and publishes punktfunk-host AND
punktfunk-client to the Gitea apt registry; new
packaging/debian/build-client-deb.sh mirrors the host script
(shlibdeps auto-Depends — GTK4/libadwaita/SDL3/FFmpeg/PipeWire
sonames; no NVIDIA filter, the client links no CUDA). Built and
inspected locally on Ubuntu 26.04.
- punktfunk.spec gains a "client" subpackage (binary + desktop entry +
udev rule); rpm.yml's publish loop picks it up unchanged.
- New shared assets: packaging/linux/io.unom.Punktfunk.desktop and
scripts/70-punktfunk-client.rules — DualSense hidraw uaccess (USB +
Bluetooth, steam-devices style) so SDL's HIDAPI driver gets
touchpad/motion/lightbar/triggers instead of degrading to evdev.
- Builder images learn the client link deps (rust-ci already had
them; fedora-rpm adds gtk4/libadwaita/SDL3-devel) with idempotent
install steps in deb.yml/rpm.yml since jobs run against the
previous push's image.
Workspace check CI (build/clippy/test) already covers the crate since
f09def4.

The host requests a 32 MB SO_SNDBUF, but the kernel clamps it to net.core.wmem_max
(~416 KB on a stock box) — so high-bitrate frames overflow the socket buffer and
the host drops a large fraction of packets on send (measured 28.5% loss / 54k
dropped at 1 Gbps to a clean LAN client on a fresh Bazzite box). scripts/99-punktfunk-net.conf
fixes it (32 MB caps) but the packages never installed it. Ship it to
/usr/lib/sysctl.d/ (auto-applied at boot by systemd-sysctl) and apply it in the
deb/rpm postinst. This is the dominant cause of the sub-Gbps ceiling on an
untuned host.

Mirrors the apt pipeline for Fedora Atomic / Bazzite. New `rpm` workflow builds
the host RPM in a Fedora 43 builder image (ci/fedora-rpm.Dockerfile — matches
Bazzite's libavcodec.so.61, with a self-contained 16-symbol libcuda link stub so
no NVIDIA packages are needed in CI) and uploads to Gitea's public RPM registry
(group "bazzite") on every main push (rolling 0.0.1-0.ciN.<sha>) and v* tag
(clean X.Y.Z-1). Bazzite hosts then track it with `rpm-ostree upgrade`.
- packaging/rpm/build-rpm.sh: git-archive tarball + rpmbuild (--nodeps, since the
toolchain is rustup + dnf, not RPMs); copies to dist/, asserts no cuda/nvidia leak.
- punktfunk.spec: overridable pf_version/pf_release for CI snapshots; exclude
libcuda.so from auto-Requires (NVENC/EGL come from the driver, out of band) —
same NVIDIA filter as the .deb; fix a bogus changelog weekday.
- docker.yml builds+pushes the new fedora-rpm image; packaging README + rpm/README
document the rpm-ostree install/update path (recommended option).
Builder image seeded to the registry so rpm.yml's first run finds it. RPM build +
clean-Requires verified locally in the image (libavcodec.so.61 / libavutil.so.59,
no cuda).

punktfunk-host builds unchanged against either FFmpeg 7.x (libavcodec 61) or 8.x
(libavcodec 62) — ffmpeg-sys-next auto-detects the system version, and the host's
ffmpeg FFI only touches long-stable APIs. Confirmed by building + running live on a
Bazzite F43 box (FFmpeg 7.1.3): full gamescope capture → zero-copy dmabuf→CUDA →
NVENC H.265 at 1280x720x60, p50 ~0.96 ms. Just doc/spec accuracy, no code change:
- encode/linux.rs + CLAUDE.md: drop the "FFmpeg 8 only" claim; note 7.x/8.x both work.
- rpm spec: add the missing zero-copy GPU build deps the link actually needs —
pkgconfig(gl) + pkgconfig(gbm) (mesa) — and document that -lcuda needs libcuda.so at
link time (NVIDIA host, or the CUDA toolkit stub on a headless COPR/koji builder).
Tracked for a proper fix: make the cuda/gbm/GL FFI dlopen-based like khronos-egl so
the RPM builds on a GPU-less host.

Roadmap #3 (install on other devices). Bazzite already ships gamescope + PipeWire + the
NVIDIA stack, so the host slots in with minimal new deps (ffmpeg-libs from RPM Fusion + opus
+ libei).
- packaging/rpm/punktfunk.spec — builds punktfunk-host from source (cargo), installs the
binary + udev rule + systemd user unit + headless helpers; Requires/Recommends mapped from
the Ubuntu bootstrap deps to Fedora.
- packaging/bootc/Containerfile — layer punktfunk into a bazzite-nvidia bootc image for
atomic, image-based installs.
- packaging/bazzite/host.env — gamescope-default appliance config (spawned per session).
- packaging/copr/ + packaging/README.md — COPR build-from-SCM settings + install docs
(rpm-ostree and bootc paths), and why not Flatpak.
- LICENSE-MIT + LICENSE-APACHE — materialize the declared `MIT OR Apache-2.0` (was unfiled);
the RPM ships them.
Not buildable on the Ubuntu dev box (no rpm tooling) — the COPR/Fedora build is operator-run;
all spec-referenced files verified present and the cargo build is green.
