Backtest demo — favorites buyer

This is not a real trading strategy. It exists so simmer backtest --demo produces a meaningful report (decisions, trades, settlements, hit_rate, pnl, baselines) with no network access and no tape download.

Each tick it buys a small fixed amount of YES on the most liquid markets trading as favorites (YES price in a mid-to-high band), skipping anything it already holds. Run against the bundled 10-market demo slice, a handful of those favorites resolve YES (wins) and a handful resolve NO (losses), so the demo shows a realistic mixed outcome rather than "0 trades, stayed flat".

Entrypoint: favorites_demo.py (reads SIMMER_API_URL / SIMMER_API_KEY from the replay harness; accepts and ignores --live / --quiet).
