Surface pixelpass screen-sharing from inside a peerspeak room. peerspeak owns
voice, pixelpass owns pixels — they're never Cargo deps of each other; the
contract is pixelpass's CLI flags + its `--output json` stdout stream.
Modelled on Discord: multiple simultaneous sharers, a 🔴 Live badge + 👁 Watch
on each sharing peer's card, and in-progress shares visible to late joiners.
- New `src/screenshare` module: pure `parse_pixelpass_event` seam + `pixelpass_path`
discovery (13 unit tests), async `spawn_host` (→ ticket) and `spawn_viewer`
(→ parse connected{url} → open mpv, vlc fallback). No new deps.
- Sharing rides presence: `PeerState.sharing: Option<ticket>` (serde-defaulted),
so the existing gossip re-announce delivers the offer to late joiners for free
and a PeerUpdated fires on start/stop — no separate gossip message needed.
- core: Start/Stop/ViewShare commands; host + viewer children tracked in the
session, killed on stop/leave (kill_on_drop backstop). Viewer limit left to
pixelpass's bandwidth-measured cap.
- UI: Share/Stop button (graceful "needs pixelpass" disabled state), Live badge
+ Watch on peer cards, Sharing badge on the self card. Verified by screenshot.
- config: optional `pixelpass_path` override (hand-editable).
Tests-green; the 2-machine gossip/remote path is not yet field-verified.

Approach B: peerspeak spawns pixelpass --host --output json, scrapes the
ticket from its JSON stdout, and distributes it over the existing gossip
plane as a ScreenShareOffer; peers get a one-click pixelpass viewer.
Mutually optional, runtime-only coupling -- neither tool is a Cargo
dependency of the other; the contract is pixelpass's CLI + JSON protocol.
Video-only, separate viewer window, PATH binary discovery. Not yet built.
