enricobuehler	946f1b3d69	fix(steamdeck): build the host with vulkan-encode, and wire up what it needs to actually engage ... The SteamOS scripts built the host featureless, so PlatformAuto could never pick the Vulkan Video backend (default-on since 84329205) and every session silently ran libav VAAPI — unlike the deb/arch/rpm/sysext builds, which all pass the feature. Three gaps, found live on a Deck host: - install.sh/update.sh: cargo build with --features punktfunk-host/vulkan-encode (matches the packaged builds; pure-Rust ash, no new system dep). - host.env: RADV_PERFTEST=video_encode — Van Gogh RADV still gates VK_KHR_video_encode_* behind it, so without it the backend can't open and falls back to VAAPI. Harmless where encode is exposed by default. - io.unom.Punktfunk.Host.desktop (Exec rewritten to this install's binary): KWin only grants zkde_screencast_unstable_v1/org_kde_kwin_fake_input to an exe a .desktop authorizes — without it Desktop-Mode capture fails outright and a mid-stream Game↔Desktop switch strands the stream on the old backend. update.sh retrofits the last two idempotently so existing installs get them without a reinstall. Validated on a SteamOS 3.8.14 Deck (Van Gogh): Vulkan HEVC opened on both the KWin and gamescope paths at 5120x1440 — in-place ABR reconfigure (no IDR, no encoder rebuild) vs the VAAPI path's full teardown per ABR step, and Desktop capture came up without a re-login.

enricobuehler	e235177bf8	feat(steamdeck): one-command host install + docs (build-on-device) ... SteamOS is immutable read-only Arch, and the Deck is AMD (VAAPI) — so none of the checked-in packaging (arch/sysext is NVENC-first + client-oriented, deb/rpm are soname-mismatched) actually installs a working host on a Steam Deck. The proven path (distrobox-built native binary + systemd-run units) was 100% manual. Make it one command. - scripts/steamdeck/install.sh — idempotent installer: ensure the pf2 Debian-trixie distrobox + toolchain → build host (+web console) → write config (generated web login password) → raise UDP buffers to 32 MB + udev + input group (sudo, skipped gracefully if unavailable) → install + start punktfunk-host / punktfunk-web systemd USER services with linger. Flags: --open (accept unpaired clients), --no-web, --src=DIR. Builds on-device so a rebuild always matches the running SteamOS (no prebuilt-binary fragility across OS updates); VAAPI on the Deck's AMD GPU. - scripts/steamdeck/update.sh — rebuild from current source + restart (config/pairings persist). - scripts/steamdeck/README.md — deep reference (why on-device, what's installed, gotchas). - docs-site: new "Steam Deck (Host)" guide + sidebar entry; install.md splits Arch from the Steam Deck host path; packaging/arch/README points Deck-host users here and corrects the stale "NVENC-only" note (VAAPI host encode landed). Live-validated on the Deck: installer runs clean, both services come up, host listens (QUIC :9777 + mgmt :47990), web serves (302→login); on a client connect it takes over the Game-Mode gamescope session at the client's mode, captures via PipeWire, and VAAPI-encodes (hevc_vaapi) — full pipeline confirmed in the host journal.
