fix(packaging): install punktfunk-host on Ubuntu 24.04 LTS via a noble builder that bundles FFmpeg 8

The host .deb was built on the Ubuntu 26.04 rust-ci image, so dpkg-shlibdeps baked in `Depends: libavcodec62` (FFmpeg 8) and a glibc-2.41 floor — making it uninstallable on Ubuntu 24.04 LTS (FFmpeg 6.1 / libavcodec60, glibc 2.39; apt reports the deps as "too recent"). The source floor (ffmpeg-next 8, libavcodec >=61 APIs) means a straight 24.04 rebuild would fail too. Build the host on Ubuntu 24.04 instead — lowering the glibc floor to 2.39 so one binary runs on 24.04 -> 26.04 — and bundle a from-source LGPL FFmpeg 8 into the package so it no longer depends on the distro libav*. Everything else the host links is soname-compatible on 24.04 (opus is vendored via cmake; NVENC/libcuda are dlopen-only, never link-time), and the only FFmpeg encoders used are *_nvenc / *_vaapi (software H.264 fallback is the BSD-2 openh264 crate, not FFmpeg libx264), so an LGPL build keeps the bundle license-clean. - ci/rust-ci-noble.Dockerfile (new): ubuntu:24.04 builder; nv-codec-headers + FFmpeg 8 (--enable-nvenc --enable-vaapi, shared) -> /opt/ffmpeg; PKG_CONFIG_PATH. - packaging/debian/build-deb.sh: BUNDLE_FFMPEG=1 copies libav*/libsw*/libpostproc into /usr/lib/punktfunk-host, patchelf-sets the rpath ($ORIGIN per-lib + binary --force-rpath), feeds them to dpkg-shlibdeps (captures libva2/libdrm2), and drops the libav* sonames from Depends. Normal (non-bundle) path unchanged. - .gitea/workflows/deb.yml: split into build-publish (client/web/scripting on the 26.04 image) and build-publish-host (noble image, BUNDLE_FFMPEG=1); parallel, identical version step, same apt distribution -> one universal host .deb. - .gitea/workflows/docker.yml: build+push punktfunk-rust-ci-noble. - packaging/debian/README.md: document the 24.04 LTS path + bundled local build.

 # LTS builder for the punktfunk HOST .deb — Ubuntu 24.04 (noble), the current Ubuntu LTS.
 #
 # WHY THIS EXISTS (see packaging/debian/README.md → "Ubuntu 24.04 LTS"):
 # The default builder (ci/rust-ci.Dockerfile) is Ubuntu 26.04, so the host .deb it produces bakes
 # in a glibc 2.41 floor and a hard `Depends: libavcodec62, …` (FFmpeg 8). Ubuntu 24.04 LTS ships
 # glibc 2.39 and FFmpeg 6.1 (libavcodec60), so that .deb is uninstallable there — apt reports the
 # deps as "too recent". Building the host on 24.04 instead lowers the glibc floor to 2.39 (the
 # binary then runs on 24.04 → 26.04), and the ONE library 24.04 is too old for — FFmpeg — is built
 # from source here and BUNDLED into the .deb (packaging/debian/build-deb.sh, BUNDLE_FFMPEG=1), so
 # the package no longer depends on the distro's libav* at all. Everything else the host links
 # (PipeWire, Wayland, xkbcommon, GL/EGL/GBM, Vulkan; opus is vendored via cmake) is soname-compatible
 # on 24.04, so this ONE universal host .deb replaces the 26.04-built one for every Ubuntu user.
 #
 # libcuda is deliberately NOT provided: the host dlopen's libcuda.so.1 at runtime (pf-zerocopy /
 # pf-encode) and never link-imports it, so — unlike the full-workspace rust-ci image, which builds
 # tests that DO link a cuda stub — this host-only build needs no NVIDIA driver package. NVENC/EGL
 # come from whatever driver the target runs, out of band.
 #
 # Rebuilt+pushed by .gitea/workflows/docker.yml (matrix: punktfunk-rust-ci-noble); consumed by the
 # `build-publish-host` job in .gitea/workflows/deb.yml. Bootstrap: like rust-ci, the first deb.yml
 # run after this image is added uses the image from a PRIOR docker.yml push — seed it once manually
 # (docker build -f ci/rust-ci-noble.Dockerfile -t … ci && docker push) before the host job can run.

 //! Plugin registry (plugin-ui-surface design): an in-memory, lease-based directory of running
 //! `punktfunk-plugin-*` processes and the loopback UI each one serves.
 //!
 //! A plugin (an out-of-process script under the scripting runner, RFC §8) that wants a UI serves
 //! it on a **loopback** port behind a per-boot secret, then **registers** here — `{title, ui:{port,
 //! secret, icon}}` — over the admin/loopback lane it already holds via the SDK. The web console
 //! reads [`list_plugins`] to grow a nav entry and reverse-proxies to the port (fetching the secret
 //! from [`get_ui_credential`] server-side, never exposing it to the browser). The host itself never
 //! dials the plugin, never health-checks it, and never persists any of this: it is a phone book with
 //! expiry.
 //!
 //! Lease model (design §3, D8): a registration lives for [`LEASE_TTL`]; the plugin renews with the
 //! same idempotent `PUT` every 30 s. Expiry is **lazy** — a crashed plugin's entry simply stops
 //! listing once stale; there is no reaper task and nothing to persist across a host restart (the
 //! supervised plugin re-registers on its next tick). Every consumer dials `127.0.0.1:<port>` only —
 //! a registration stores a *port*, never an address, so it can never point the proxy elsewhere (D5).
 //!
 //! Auth: these routes carry no special handling — they are outside the [`super::auth::cert_may_access`]
 //! read-only allowlist, so the middleware confines them to a **bearer + loopback** peer like every
 //! other mutation. LAN clients have no business here.

 band, like on the RPM side.
 ## Ubuntu 24.04 LTS (and why it needs a special build)
 `punktfunk-host` needs **FFmpeg 8** (libavcodec62), but Ubuntu 24.04 LTS ships FFmpeg 6.1
 (libavcodec60). So a host `.deb` built the obvious way — on the same Ubuntu 26.04 image as the
 client (`ci/rust-ci.Dockerfile`) — declares `Depends: libavcodec62, …` and a glibc-2.41 floor that
 24.04's apt can't satisfy ("the required packages are too recent"). To fix that, the host `.deb` is
 instead built on an **Ubuntu 24.04 image** (`ci/rust-ci-noble.Dockerfile`) that carries a from-source
 FFmpeg 8, and that FFmpeg is **bundled into the package** (`build-deb.sh BUNDLE_FFMPEG=1` → the
 libav* land in `/usr/lib/punktfunk-host`, the binary's rpath points there, and the libav* sonames are
 dropped from `Depends`). The result is **one** host `.deb` that installs on **Ubuntu 24.04 LTS through
 26.04** (glibc floor 2.39; no distro-FFmpeg dependency). The client/web/scripting `.deb`s still build
 on 26.04 (the native client needs SDL3 / GTK4 ≥ 4.20, absent on 24.04) — install the client on the box
 you stream *to*, which is independent of the host's distro.

 # Runtime is BUN: the runner `import()`s the operator's `.ts` plugin/script files directly, which

 Description: punktfunk plugin/script runner (Effect SDK on bun)
 Runs a punktfunk host's automation: loose scripts in ~/.config/punktfunk/scripts and installed
 punktfunk-plugin-* packages under ~/.config/punktfunk/plugins, each supervised (Effect fibers with
 capped-jittered restart; SIGTERM shuts the whole tree down structurally so plugin finalizers run).
 Bundles its own bun runtime (no system nodejs/bun dependency).
 .
 OPT-IN: the systemd --user unit is installed but not auto-enabled (the runner is inert until you add
 scripts or plugins). A plugin auto-wires to the host's mgmt token + identity cert on the same box —
 no env editing. Enable it with: systemctl --user enable --now punktfunk-scripting

 The console is **auto-wired** to the host on the same box: it reads the host's per-user
 `~/.config/punktfunk/{mgmt-token,cert.pem,key.pem}` (written by `serve`), serves HTTPS with the
 host's own identity cert, and proxies the loopback mgmt API with the bearer token injected
 server-side (never sent to the browser). A login password is generated on first start — read it
 with `journalctl --user -u punktfunk-web-init` (or `~/.config/punktfunk/web-password`). Then open
 `https://<host-ip>:47992` and trust the self-signed host cert once. Enable it (with the host) via
 `systemctl --user enable --now punktfunk-web`.

 run**):

 The runner discovers loose scripts under `~/.config/punktfunk/scripts` and installed
 `punktfunk-plugin-*` packages under `~/.config/punktfunk/plugins`, and supervises each as an Effect
 fiber (SIGTERM shuts the tree down structurally so plugin finalizers run). A plugin auto-wires to
 the host's mgmt token + identity cert. It's inert until you add automation, so the unit ships
 un-started; turn it on with `systemctl --user enable --now punktfunk-scripting`.

 - **First build compiles from scratch** (no split dep cache — pyrowave-sys builds a CMake tree in
  its build.rs that a crane "dummy" source would drop) and has no public binary cache, so expect a
  long initial build. `nix develop` gives incremental rebuilds.
 - **The status tray is built in its own derivation, on purpose.** `punktfunk-tray` uses `ksni`'s
  `async-io` zbus executor with no tokio runtime (by design — see `crates/punktfunk-tray/Cargo.toml`).
  Cargo unifies features across everything in one `cargo build`, so co-building the tray with the
  host would pull the host's `ashpd → zbus/tokio` onto the tray's shared `zbus`, and the tray then
  panics at startup (`there is no reactor running, must be called from the context of a Tokio 1.x
  runtime`). Building it as a separate `-p punktfunk-tray` invocation keeps its `zbus` on async-io;
  the host package copies the resulting binary into its `$out`. (The deb/rpm/arch builds co-build the
  two in one `cargo build`, so they share this latent crash on Linux — a separate fix.)
 - **The bun packages (`punktfunk-web`, `punktfunk-scripting`) — their `bun install` deps hashes.**
  Both build their `node_modules` in a *fixed-output derivation* (`bun install` needs the network +
  the read-public `@unom` npm registry). Each `outputHash` (in `packaging/nix/packages.nix`) is
  pinned to a resolved dependency set and **must be refreshed when its lockfile changes** —
  `web/bun.lock` for the console, `sdk/bun.lock` for the runner: set that `outputHash = lib.fakeHash`,
  run `nix build .#punktfunk-web` (or `.#punktfunk-scripting`), and copy the `got: sha256-…` value
  Nix prints back into the field. Everything downstream is offline (the console's codegen + vite
  build; the runner's `bun build --target=bun` bundle), so only the deps FODs ever need network.
  Both launchers exec `pkgs.bun` from the store — unlike the deb/rpm, which vendor a bun binary

 Summary:        punktfunk plugin/script runner (Effect SDK on bun)
 # Runtime is BUN — the runner import()s the operator's .ts plugin files, which only bun can do. bun
 # isn't in Fedora repos, so we VENDOR it into the package (arch-specific, not noarch). The runner
 # itself is bundled to ONE self-contained JS (effect + SDK inlined), so no node_modules ship.
 %description scripting
 The plugin/script runner for a punktfunk streaming host: it discovers loose scripts under
 ~/.config/punktfunk/scripts and installed punktfunk-plugin-* packages under ~/.config/punktfunk/
 plugins, and supervises each as an Effect fiber (capped-jittered restart; SIGTERM shuts the whole
 tree down structurally so plugin finalizers run). A plugin auto-wires to the host's mgmt token +
 identity cert on the same box — no env editing. Bundles its own bun runtime. OPT-IN: the systemd
 --user unit ships disabled (the runner is inert until you add scripts/plugins). Enable with
 `systemctl --user enable --now punktfunk-scripting`.

 ### A plugin UI in the console — `servePluginUi`
 A plugin can surface a web UI **inside the punktfunk console** — no second password or port for the
 operator. It serves the UI on a loopback ephemeral port behind a per-boot secret; `servePluginUi`
 registers it with the host, and the console reverse-proxies to it and adds a nav entry gated by the
 console's own session. Your code implements **zero human auth**.
 ```ts
 import { definePlugin, servePluginUi } from "@punktfunk/host";
 export default definePlugin({
  name: "rom-manager",
  main: async (pf) => {
    const ui = await servePluginUi(pf, {
      id: "rom-manager",
      title: "ROM Manager",
      icon: "gamepad-2",                            // a lucide icon name
      staticDir: new URL("../dist/ui", import.meta.url), // your built SPA
      fetch: (req) => appRouter(req),               // plugin-local REST/SSE (after a static miss)
    });
    try {
      await runForever();

      await ui.close();                             // deregister + stop
    }
  },
 });
 ```
 Requests reach `fetch` **prefix-stripped** (the console proxy removed `/plugin-ui/<id>`), so your app
 sees `/`, `/api/scan`, … — the original prefix is on `X-Forwarded-Prefix`. `servePluginUi` serves
 `staticDir` first (with an `index.html` SPA fallback for navigations); return `undefined` from `fetch`
 to fall through to it. Build your SPA with a relative base (`base: "./"` + hash routing) or an absolute
 `base: "/plugin-ui/<id>/"`, and expect a dark canvas. Requires the Bun runtime (the runner is bun).
