[codex] Migrate website SSG to React Router#99
Merged
Conversation
The React Router migration's boilerplate entry.client.tsx wrapped the app
in <React.StrictMode>, which the prior vite-react-ssg setup never did. In
dev, StrictMode double-invokes mount: dockview's onReady fires and
use-dockview-ready.ts destructively consumes initialPaneIds, then StrictMode
disposes and recreates dockview. The second onReady no longer sees the
'tut-main' pane id and generates a random one instead, so
PlaygroundDesktop.handleApiReady's addPanel({ referencePanel: 'tut-main' })
throws "referencePanel 'tut-main' does not exist" and the page crashes.
Production builds don't double-invoke, so this was a dev-only crash, but it
makes the desktop playground unusable under `react-router dev`.

Summary
Migrate the website static build from
vite-react-ssgto React Router Framework Mode withssr: false, including React Router route modules, client/server entries, and the build flattening step needed for Cloudflare Pages.The branch also keeps the changelog filter route client-side:
/changelog/after/*is rewritten to React Router's generated SPA fallback so the browser URL is preserved without generating HTML for every release version.Impact
react-router buildand prerender the stable static routes.Validation
pnpm --filter dormouse-website buildpnpm --filter dormouse-website testdist/_redirectspoints/changelog/after/*at__spa-fallback.html.dist/changelogonly contains the stable changelog HTML, not per-version filter pages.
