feat(audio): HDMI audio works out of the box — pipewire in ISO + router daemon + ELD boot-race heal Root cause of silent HDMI on kiosk TVs (framework-pt, LG TV): 1) fresh ISOs installed NO audio stack even though the kiosk launcher expects PipeWire-Pulse — add pipewire/pipewire-pulse/pipewire-alsa/ wireplumber/alsa-utils to the rootfs and put the archipelago user in 'audio' (linger user manager gets no logind seat ACLs on /dev/snd); 2) the kiosk's boot-time Xorg modeset races the i915→HDA audio-component bind, the ELD notify is lost, and every HDMI profile stays 'available: no' forever. Verified live: one off/on modeset re-delivers the ELD and WirePlumber immediately switches to HDMI. New archipelago-audio-router daemon (same splice-from-configs pattern as the kiosk, ISO + include_str! self-heal): routes the card to the best available HDMI profile, keeps the default sink on it, migrates live streams on hot-plug, unmutes (HDMI forced 100% — the TV owns volume), and re-modesets a connected external output once when no ELD reports a monitor. bootstrap::ensure_audio_stack() installs packages + router on already-deployed kiosk nodes via OTA (apt through systemd-run — the service sandbox keeps /usr and dpkg read-only). main.rs also spawns the pine satellite keeper.
