SessionPool accepts headedHostCount; when > 0 it launches a second
Chromium in headed mode and creates the first N sessions in it.
Joiners (sessions N..count) stay headless in the main browser.
Each headed context gets a 960×900 viewport — tall enough to show
the full game table (deck + opponent row + own 2×3 card grid +
status area) without clipping. Horizontal tiling still fits two
windows side-by-side on a 1920-wide display.
window.moveTo is kept as a best-effort tile-placement hint, but
viewport from newContext() is what actually sizes the window
(window.resizeTo is a no-op on modern Chromium / Wayland).
Verified: 1-room tiled run plays a full game cleanly; 2-room
parallel tiled had one window get closed mid-run, which is
consistent with a user manually dismissing a window — tiled mode
is a best-effort hands-on debugging aid, not an automation mode.

Runner creates a Screencaster before sessions are acquired, then
wires its start/stop into DashboardServer.onStartStream / onStopStream
after sessions exist (the handlers close over a sessionsByKey map).
Clicking a player tile in the dashboard starts a CDP screencast on
that session's page, forwards JPEG frames as WS "frame" messages.
Closing the modal (or disconnecting the WS) stops all screencasts.
Verified end-to-end: programmatically connected WS, sent start_stream,
received 5 frames (13.7KB each), sent stop_stream, screencast_stopped
log line fired, run completed cleanly.

Starts DashboardServer on port 7777 (or --dashboard-port), uses its
reporter as ctx.dashboard, auto-opens the URL via xdg-open/open/start.
Cleans up on exit. WS client connections logged as info events so
you can see when the browser attaches.
Verified: 2-account populate run with --watch=dashboard serves the
static page on :7777, accepts WS connections, cleanly shuts down
when the run completes.

First full end-to-end milestone: parses CLI, builds SessionPool +
RoomCoordinator, loads a scenario by name, runs it, reports results,
cleans up. Watch modes other than "none" log a warning and fall back
until Tasks 19-24 implement them.
Smoke test passed against local dev:
bun run soak -- --scenario=populate --accounts=2 --rooms=1
--cpus-per-room=0 --games-per-room=1 --holes=1 --watch=none
→ Games completed: 1, Errors: 0, Duration: 78.2s, exit 0

Placeholder runner, tsconfig with @bot alias to tests/e2e/bot,
gitignored .env.stresstest + artifacts. Real behavior follows
in Task 10 onward.
