Rolling-chart

[skywinder]

Add a "rolling window" mode to the Race Chart that shows scrobble counts within a configurable time period in addition to cumulative all-time data.

• New toggle in settings menu: Cumulative (default) vs Rolling Window mode
• Adjustable window size with +/- buttons (default: 12 months)
• As animation plays, data outside the window gets "forgotten", showing more current trends
• Chart title updates to reflect current mode (e.g., "Race chart (6 months)")

I like it more, since it shows dynamics of your tastes.
