Add satori+sharp OG card generation: each note gets a 1200x630 social
image showing its own plant (same deterministic geometry) beside the
title, summary, and growth stage. /og/<slug>.png per note plus a default
/og.png for other pages. Wire og:image + summary_large_image twitter
card; notes use ogType=article. Shared static SVG serializer in
plant-svg.ts (unit-tested).
