The turbo/generators package shipped without `lint` or `typecheck` scripts,
so `pnpm lint` / `pnpm typecheck` at the root silently skipped it. This
masked 2 ESLint errors (unused imports) and 11 TypeScript errors (relative
imports missing the `.js` extension required by `moduleResolution: NodeNext`,
plus JSON imports missing the `with { type: "json" }` attribute).
- Add `lint` and `typecheck` scripts to turbo/generators/package.json so the
turbo pipeline picks them up (lint: 14/14, was 13/13).
- Add `.js` extensions to 7 relative imports across config.test.ts,
lib/core-package-utils.test.ts, lib/snapshot.test.ts, and the 4 e2e tests.
- Add `with { type: "json" }` attributes to 4 snapshot JSON imports in the
e2e tests.
- Remove unused `existsSync` and `splicePluginImportsAt` imports from
lib/core-package-utils.test.ts.
- Declare `@repo/core-typescript` + `typescript` devDependencies so the
generators package can run `tsc --noEmit` for typecheck.
