David Snelling 5958502cf3 **test(tests): enhance test clarity, isolation, and robustness**
- **Test Improvements**:
  - Introduced data-clearing steps (`.clear()`) across critical test cases for ensuring better test isolation and preventing state leakage.
  - Extended support for overriding global utilities (`testUtils`) and added fallback behaviors for test vector creation.

- **Configuration Updates**:
  - Added support for `distanceFunction` as an alternative to `metric` in vector operations for consistency.
  - Adjusted and unified asynchronous `timeout` handling across test suites for predictability.

- **Purpose**:
  - These updates improve reliability, maintainability, and clarity in test cases while ensuring compatibility across diverse test environments.
