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).
