Add eslint@^8.57.0, @headlamp-k8s/eslint-config@^0.6.0, prettier@^2.8.8,
typescript@~5.6.2 as explicit devDependencies. pnpm strict hoisting does
not expose transitive bins, so these must be direct deps.
Remove vite/client and vite-plugin-svgr/client from tsconfig types; these
are transitive deps pnpm does not hoist and polaris plugin omits them.
