test(cli): import inquirerer test utils directly from @inquirerer/test

The local 'packages/cli/test-utils' barrel was a pure passthrough
re-export of @inquirerer/test, which made it look like there was a
custom test harness when there wasn't. This points cli.test.ts at
@inquirerer/test directly so it's obvious where the helpers come from,
and trims test-utils/index.ts down to the genuinely local fixture
helpers.

No behavioural change — the symbols (KEY_SEQUENCES, setupTests,
TestEnvironment) are identical.
