v2.0.0 — orbit layout (038)

Breaking: the default output is now the Orbit layout — a radial year with a stats panel, 896×300 instead of 896×150. Embeds that relied on the old height will grow; pin layout: grid to keep the classic sky, or stay on @v1 (unchanged).

What's new

• Orbit layout (default): the year wound into seven weekday rings around a sun carrying your total; month ticks; a continuously orbiting comet; a panel with active days, longest streak, best day, busiest weekday and a weekly-volume histogram.
• layout input: orbit (default) or grid. Validated before any network call.
• Grid layout is unchanged byte-for-byte and stays available via layout: grid.

@v1 keeps rendering the grid; only workflows that move to @v2 (or track @main) receive the orbit.
