Director Mode

While a run is in progress, use ↑ / ↓ to apply a live RPS bias on top of the configured stage target. The bias accumulates (e.g., three ↑ presses = +15 RPS) and is shown in the TUI and reflected in the live metrics. The bias is applied on top of the LERP'd value — the stage plan continues to run unaffected.
