Fix unfulfilled lint expectation in crates/comenqd/tests/util.rs

[coderabbitai]

Description

CI compilation is failing due to an unfulfilled lint expectation in the test utilities file.

Error Details

error: this lint expectation is unfulfilled
Error:   --> crates/comenqd/tests/util.rs:16:14
   |
16 |     #[expect(dead_code, reason = "Constructed in integration tests but unused here")]
   |              ^^^^^^^^^
   |
   = note: Constructed in integration tests but unused here
   = note: `-D unfulfilled-lint-expectations` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(unfulfilled_lint_expectations)]`

Impact

This error is preventing:

• Successful compilation of the test suite
• CI pipeline completion
• PR merge capability

Suggested Solutions

The compiler suggests three possible fixes:

1. Remove the #[expect(dead_code)] attribute if the code is now being used
2. Replace with #[allow(dead_code)] if the code should remain potentially unused
3. Add #[allow(unfulfilled_lint_expectations)] to override the strict warning
