`npm run build` now runs `typecheck` first, so the Docker image is built through the
same gate as local dev — until now the image was a bare `vite build`, and esbuild
strips types without checking them.
typecheck covers three projects: src, the Node-side build configs (new
tsconfig.node.json — vite.config.ts/vitest.config.ts were type-checked by nothing),
and e2e. knip moves from `npx knip@latest` to a pinned devDependency so the gate
stops depending on the network and on whichever version shipped that morning.
