Walkthrough

Added isolated Vitest coverage for query parameter array serialization. The tests define a local serializeArrayQuery helper and verify string arrays, numeric arrays, and empty arrays.

The new test suite can pass while the production query serialization behavior is incorrect. Update it to call the production helper before relying on this coverage.

Test withQuery instead of a local serializer.

serializeArrayQuery does not exercise src/utils.url.ts:withQuery. The production helper returns a full URL, uses URLSearchParams, and returns the input URL for an empty array. Import withQuery and assert the repeated-key, numeric, and empty-array outputs directly.
