fix(search): check HTTP status code and add test coverage

Switch queryAPI from httpClient.Get to httputil.Do so 429 responses
trigger the existing retry/rate-limit logic. Add an explicit status
check after the request so non-200 responses (429, 500, …) return a
meaningful error instead of falling through to a confusing JSON-parse
failure. Add search_test.go with 13 table-driven tests covering 200 OK,
empty results, 429, 500, invalid JSON, network errors, flag mapping,
and SearchOnline partial-success; statement coverage is 94.2%.
