Merge branch 'abhi/builder-integration-test-part-1' into abhi/builder-integration-test-part-2

- Replace `any` types with proper interfaces and `unknown`
- Add `createExecutionResult()` helper for consistent test data
- Replace setTimeout-based microtask flushing with `queueMicrotask()`
- Use `vi.waitFor()` for reliable async assertions
- Remove redundant `cleanup()` call in beforeEach
- Split combined test case into separate assertions
