Completes the GameStream-opt-in posture (0de648f) on the SteamOS path: the installer keeps
Moonlight compat on by default (`serve --gamestream`, the Deck commonly streams to Moonlight),
but `--no-gamestream` now installs a secure native-only host with no GameStream on-path surface
(plain-HTTP pairing / legacy GCM nonce reuse — security-review #5/#9; native clients only).
Documented in the installer --help; the SteamOS host doc references it.

Follows the security audit (#5/#9): the GameStream-compat plane carries inherent on-path weaknesses
that can't be fixed on the wire without breaking stock Moonlight — its pairing runs over plain HTTP
(#9, MITM-able during the pairing window) and its legacy control encryption can reuse GCM nonces (#5,
a passive eavesdropper can recover/forge input). The native punktfunk/1 plane (SPAKE2 PIN pairing +
per-direction AEAD nonces) has neither. So flip the default to secure-by-default:
- `serve` → native punktfunk/1 plane + management API ONLY (no GameStream surface).
- `serve --gamestream` → ALSO the GameStream/Moonlight-compat planes (nvhttp pairing, RTSP, ENet
control, _nvstream mDNS). Opt-in, logged with a trusted-LAN caveat. `--moonlight` is an alias.
- The native plane is now ALWAYS on in `serve` (`--native` is a kept-for-compat no-op); the unified
GameStream+native host is `serve --gamestream`.
`gamestream::serve` gates the GameStream spawns (nvhttp/rtsp/control/mdns) on the flag; the native
plane + mgmt + native-pairing handle always run.
To avoid silently regressing validated Moonlight deployments, the explicit deployment configs PRESERVE
Moonlight via `--gamestream` (each documents dropping it for a secure native-only host): the Linux
systemd unit, the Steam Deck installer, and the Windows service default (DEFAULT_HOST_CMD). The bare
`serve` default (new/manual use) is secure.
Docs swept to match (host-cli, moonlight, quickstart, install, packaging READMEs, CLAUDE.md, README,
…): Moonlight setup now instructs `--gamestream`; native/console refs use bare `serve`. OpenAPI
regenerated (a stale "run `serve --native`" string). fmt + clippy clean; 94 host tests green.

The management console is a Nitro `node-server` build (per web/vite.config.ts) — it must be
run with `node`, not `bun`. Run under bun it 500s on every page render with
"Cannot find package 'srvx'": bun mis-resolves Nitro's externalized server deps from the
nested SSR chunk at request time. (This was pre-existing — the old manual pfweb.sh ran it
with bun too.)
- Provision `nodejs` in the pf2 distrobox; run the web service with `node .output/server/index.mjs`.
- Use `enable` + `restart` (not `enable --now`) so re-running the installer actually applies
unit-file changes instead of no-opping against the running service.
Verified on the Deck: web `/login` now returns 200 (was 500), "Listening on http://0.0.0.0:3000",
no srvx error.

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.
