/**
* Presence roster e2e (collab-presence 0001): two tabs of the real React app on
* the SAME project file share one collab room over the default BroadcastChannel
* provider — each tab's PresenceRoster chip must show the OTHER user, and a tab
* leaving must drop off the peer's roster promptly (pagehide broadcast, not the
* 30s awareness timeout).
*
* Uses pl_editor (demo.kicad_wks): it is in COLLAB_TOOLS and is the smallest
* wasm, so the two boots stay cheap. Identity comes from the `?user=` slug
* (the e2e isolation hook config.ts already honors).
*
* Provider-agnostic: BC (default checkout) removes instantly via the pagehide
* broadcast; partykit removes when the server sees the WS close — measured
* ~5-8s under local wrangler dev (immediate close on real tab close; an
* about:blank navigation can BFCache the page and stretch this to ~15s, which
* is why the leave step CLOSES the tab).
