/**
 * Tests for daemon/main.ts subcommand routing.
 *
 * The `status` and `bg` subcommands trigger dynamic imports of `cli/bg.ts`
 * 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.
