* fix: merge tsconfig.base.json into tsconfig.json with full compiler options

The cherry-pick from 637c908 dropped jsx/strict/etc settings when removing

+ * which depends on `envUtils.ts` → `lodash-es/memoize.js` (unavailable in
+ * raw test context without `bun run dev`'s define flags). We test only the
+ * self-contained subcommands: help and unknown.
