Star History Chart (self-hosted, never breaks)

Add a "Stargazers over time" chart that renders from a static SVG committed to the repo and refreshes itself weekly — no external chart service, no broken images.

Why this exists

GitHub now restricts the /stargazers endpoint to a repository's own admins and collaborators. Unauthenticated requests return {"message":"Requires authentication"}, which breaks every third-party live-chart service (star-history.com free tier, starchart.cc, etc.) for all repos. The only reliable fix is to generate the chart yourself with an authenticated token and commit a static image. Inside GitHub Actions, the repo's own GITHUB_TOKEN can read its own stargazers, so the whole thing runs with zero secrets to configure.
