heatmap 0.1.1: a ramp for the Auto theme

[hamzafer]

What changed

With the Auto theme, heatmap fell back to its dark ramp. On a light terminal that made the quietest days the darkest, so they looked boldest.

• New rampFor(theme): dark… and light… themes keep their ramps; Auto or an unreadable theme gets an auto ramp
• The auto ramp keeps one lightness (contrast about 3.8:1 on white, 4.4:1 on dark) and only raises saturation, from near gray to full orange, so busier reads busier on any background. Square size still separates the two halves
• heatmap 0.1.1 (plugin.json, marketplace, site page); docs and spec updated

Checklist

• claude plugin validate mods/heatmap passes
