Adds negotiated 5.1/7.1 surround to the punktfunk/1 protocol and every client (previously stereo-only): - core: new shared `audio` layout table (LAYOUT_51/71 + identity multistream mapping, canonical wire order FL FR FC LFE RL RR SL SR); Hello/Welcome `audio_channels` negotiation via the trailing-byte back-compat pattern (old peers fall back to stereo); C-ABI `punktfunk_connect_ex6`, `punktfunk_connection_audio_channels`, and in-core multistream decode `punktfunk_connection_next_audio_pcm` for embedders without a multistream Opus decoder. Real-libopus channel-identity round-trip test. - host: native audio thread captures + Opus-(multi)stream-encodes at the negotiated count (with a cross-session cached-capturer channel-mismatch fix); GameStream surround unified onto the safe `opus::MSEncoder`, dropping `audiopus_sys` (~4 unsafe blocks) and un-gating Windows GameStream surround; WASAPI loopback capture relaxed to 2/6/8 with the correct dwChannelMask. - clients: Linux (PipeWire), Windows (WASAPI), Android (AAudio) decode via `opus::MSDecoder` + render multichannel; Apple decodes in-core to PCM → AVAudioEngine with an explicit wire-order channel layout; each gains a Stereo/5.1/7.1 setting. `punktfunk-probe --audio-channels N` is the headless validator. Verified on Linux: core/host/linux/probe test suites + the Android Rust (cargo-ndk) build, clippy -D warnings, and rustfmt all green. Windows/Apple builds, all on-glass checks, and the live native loopback are pending (CI / a free box). Also lands the concurrent in-tree HEVC 4:4:4 host work (PUNKTFUNK_444): it shares the same touched files (quic.rs, punktfunk1.rs, encode/*, ...) and so cannot be committed separately from the surround changes.

# DBUS at it), so a box that flips between Steam Gaming Mode and a KDE/GNOME desktop is followed
|

|

# changes. Requires the headless-appliance prereqs (linger + multi-user.target — see

# Mutter creates the per-client virtual output via its `RecordVirtual` D-Bus API (a virtual

# monitor alongside any real one), and input goes through the RemoteDesktop portal (libei). On a
