feat(packaging): bundle the web console into the RPM / Arch / bootc host packages 
The punktfunk-web management console (pairing + status) shipped only via apt. Extend it
to the other HOST packaging methods, mirroring the Debian punktfunk-web .deb (flatpak is
the client, correctly excluded):

- rpm/punktfunk.spec: new noarch `punktfunk-web` subpackage (the .output bundle + a
  /usr/bin/punktfunk-web-server node launcher + both systemd --user units + web-init.sh +
  web.env.example), gated behind `%bcond_with web`. OFF by default because building the
  Nitro/Node SSR bundle needs `bun`, which a plain rpmbuild / COPR mock chroot lacks. Host
  package weak-Recommends punktfunk-web.
- ci/fedora-rpm.Dockerfile: install bun (+ unzip) so the CI builder can build the console.
- rpm.yml: build `PF_WITH_WEB=1` (Prep bootstraps bun to stay green pre-image-rebuild); the
  publish loop already globs the new noarch rpm into the registry. build-rpm.sh: `--with web`
  when PF_WITH_WEB=1.
- bootc/Containerfile: install from the Gitea RPM registry (which carries punktfunk-web)
  instead of COPR — `dnf5 install punktfunk punktfunk-web`.
- arch/PKGBUILD: opt-in `punktfunk-web` split member (PF_WITH_WEB=1 appends it + bun) so a
  default makepkg still builds host+client with no JS tooling — matching the spec's bcond.
- docs: packaging/README, rpm/README, copr/README (the no-bun caveat), bazzite/README
  (Path B rewritten COPR→Gitea registry), arch/README — enable + journal-password steps.

Reviewed across methods by an adversarial multi-agent pass (rpm/ci/arch/bootc/consistency
lenses, each blocking finding 3x-verified); fixed the two it confirmed real — the Arch
bun-mandatory regression (now opt-in) and the stale COPR wording in bazzite Path B.

# punktfunk — low-latency desktop/game streaming host (RPM for Fedora / Bazzite)
#
# Builds `punktfunk-host` from source with cargo and installs the binary, the
# uinput udev rule (virtual gamepads), the systemd *user* unit, and the headless
# session helpers. Designed for COPR (build-from-SCM): COPR clones the repo and
# runs this spec; `cargo build` fetches crates over the network (COPR allows it).
#
# DEPENDENCIES NOT IN BASE FEDORA:
# * ffmpeg / ffmpeg-libs with NVENC — from RPM Fusion *nonfree*. Enable it in
# the COPR project (External Repositories) and on the target host.
# * The NVIDIA driver (libnvidia-encode / libEGL_nvidia) — present on Bazzite's
# -nvidia images; on plain Fedora install akmod-nvidia + xorg-x11-drv-nvidia-cuda.
#
# Bazzite already ships gamescope, PipeWire and the NVIDIA stack, so on Bazzite the
# only new runtime bits are ffmpeg-libs (RPM Fusion) + opus + libei.

%description
punktfunk is a Linux-first, low-latency desktop and game streaming host. It speaks
the Moonlight/GameStream protocol (pair a stock Moonlight client) and its own native
punktfunk/1 protocol (GF(2^16) Leopard FEC + AES-GCM, mid-stream mode renegotiation,
client microphone passthrough). Each session gets a virtual output at the client's
exact resolution and refresh via a per-compositor backend (KWin, gamescope, Mutter,
Sway/wlroots), captured zero-copy (dmabuf -> CUDA -> NVENC) and split-encoded above
~1 Gpix/s. Input (mouse/keyboard/gamepads) is injected back into the session.

Summary: Low-latency desktop/game streaming client (punktfunk/1, GTK4)
# Audio playback / mic capture want the PipeWire daemon; degrade gracefully without it.
Recommends: pipewire
Recommends: wireplumber
%description client
The native Linux client for punktfunk. Discovers hosts on the LAN (mDNS), trusts
them via certificate pinning with a SPAKE2 PIN pairing ceremony, and streams HEVC
video (GF(2^16) Leopard FEC + AES-GCM over UDP, QUIC control plane) with Opus
audio, microphone passthrough, and full gamepad support including DualSense
touchpad, motion, adaptive triggers and lightbar through SDL3. The host creates a
virtual output at exactly this client's resolution and refresh rate — no scaling.

# Runtime is plain node (the .output is portable JS — bun is only the build tool). Fedora 41+
# ships nodejs >= 20, which the node-server build needs.
Requires: nodejs
%description web
The browser console for a punktfunk streaming host: status, paired devices, and the SPAKE2
PIN pairing flow every client needs. Runs as a systemd --user service on port 3000, login-gated
(a password generated on first start), proxying the host's loopback HTTPS management API with a
bearer token injected server-side (never sent to the browser). Auto-wired to the host on a
packaged install — it sources the host's mgmt token and a generated login password, no env
editing. Enable with `systemctl --user enable --now punktfunk-web`.
