feat(api): server-rendered OG image of all-time contribution graph

Browse Source 
Add /v1/og/contributions.png endpoint that builds an SVG of the
all-time weekly contribution graph (one row per year) from daily
counts, then rasterizes to PNG via resvg. Served with 1h cache.

Add og:image and twitter:card meta tags to index.html pointing at
the endpoint.
