test(integration): add fixtures for directory-paths tests

Add nested directory and extension test fixtures:
- fixture/nested/suite1.bench.js and nested/deep/suite2.bench.js
- fixture/extension-test.bench.mts and extension-test.bench.cts

Update directory-paths.test.ts to use fixtures where possible.
Note: The default pattern test still needs dynamic files since it tests
discovery relative to cwd.
