Vanadium forbids direct UDP for WebRTC, and mobile and company networks often
block direct connections; the only route then is a relay reached over TCP.
- server/turn.ts: STUN and TURN on one port, over UDP and TCP, with
short-lived credentials from /api/turn, quotas and a peer filter
- The browser build fetches credentials and offers the relay automatically
- Stats for nerds says when a stream is relayed and how the relay is reached
- Tests: a TURN client over UDP and TCP, and a browser limited to the relay
over TCP in the web E2E

A stream counted as live as soon as its track was announced, before any route
existed, so a viewer whose connection never came up saw a black picture.

Codecs, picture size and frame rate, bitrate, loss, jitter and the network
path, per viewer for the sharer.

The browser build uses it automatically, so no outside server is contacted.
Covered by unit tests and a two-browser step in the web E2E.

- Start dialog with source list, live preview, sound and quality choices
- Sound on Linux through PipeWire: one program or everything except this
app, fed into a virtual microphone and kept linked as programs come and go;
system loopback on Windows; stereo Opus
- A sharer's tile shows the picture; clicking it opens a large view with the
other tiles as a strip. Own stream is previewed in the own tile
- Stream volume for viewers, watch and stop from the profile panel
- Unit tests for the PipeWire link planner; the proxy test no longer writes to
the root channel other tests listen in

- Signals travel as Mumble plugin data (compressed, chunked under Murmur's
1000 byte limit); the picture goes directly to each viewer over WebRTC
- Toolbar button with a source picker in the desktop app, an indicator next to
people who share, click to watch, a view above the chat with full screen
- Late joiners learn about running streams; moving, stopping or disconnecting
ends them for viewers
- A note about IP addresses before the first use, optional STUN server setting
- Unit tests for the signal codec and an E2E with two app instances
