packaging: add test-pack split PKGBUILD (peerspeak + pixelpass)

One `makepkg -si` from packaging/test-pack/ builds and installs both
peerspeak and pixelpass from the public gitbutter repos over https, so a
tester can clone the repo and get a working voice+screenshare pair in one
command. pixelpass installs to /usr/bin so peerspeak's screen-share button
finds it.

+# PeerSpeak + PixelPass — CachyOS/Arch test pack
+
+A single **split PKGBUILD** that builds the latest code from the public gitbutter
+repos and installs **both** programs at once:
+
+- `peerspeak` — decentralized P2P voice chat
+- `pixelpass` — P2P screen sharing (peerspeak launches it for the screen-share button)
+
+## Build & install (one command)
+
+```sh
+git clone https://gitbutter.xyz/mollusk/peerspeak.git
+cd peerspeak/packaging/test-pack
+makepkg -si
+```
+
+`makepkg -si` auto-installs every dependency via pacman before building —
+including the Rust toolchain itself (the `cargo` makedepend is provided by the
+`rust` package), `git`, `pkgconf`, pipewire + opus for peerspeak, and the
+gstreamer/VA-API stack for pixelpass. The only prerequisite is the `base-devel`
+group (which provides `makepkg`). If you already use `rustup`, that satisfies the
+`cargo` makedepend and the `rust` package won't be pulled in — no conflict.
+
+When it finishes you'll have `peerspeak` and `pixelpass` on your PATH at
+`/usr/bin`. To rebuild later with fresh upstream code, re-run `makepkg -si`; the
+git sources re-pull `main` and the version bumps automatically.
+
+> Skip the test step with `makepkg -si --nocheck` for a faster build.
+
+## Running the cross-internet test
+
+1. Launch `peerspeak` on both machines.
+2. One person **creates** a room and shares the room code/ticket with the other.
+3. The other **joins** with that code.
+4. iroh does NAT hole-punching automatically; if a direct path can't be made it
+   falls back to a public n0 relay — **no port forwarding required**.
+5. Allow the app through any local firewall if prompted (outbound UDP / QUIC;
+   nothing needs to be opened inbound for relay mode).
+
+### What we're smoke-testing
+- Two real humans, two networks, over the internet.
+- Mic capture + remote playback both directions, no crackle/dropouts.
+- Mute / deafen, push-to-talk.
+- Text chat in-room.
+- Avatars (presets + custom upload) show up on the other side.
+- Screen share: click the screen-share control → it launches `pixelpass`; the
+  viewer opens in `mpv` on the receiving side.
+- Notification chimes (join/leave/etc.).
+- Leave / rejoin cleanly.
+
+If anything misbehaves, grab the log path peerspeak prints on startup and the
+exact repro steps.
