Use indexed appends instead of primordial push calls when collecting
matching values in URLSearchParams.getAll(). This reduces the cost of
reading repeated query parameters while preserving result order.

Local benchmarks on Apple M2/macOS with V8 15.6 show higher throughput:

• Existing two- and three-match workloads: +20.4% and +29.4%.
• Consumed-result reads with multiple matches: +28.5–106.8%.
• Parsing a fresh query and retrieving 256 matching values: +8.9%.

Across 36 cases and 4,320 samples, nine gains were confirmed in both
comparison directions after Holm correction. No corrected-significant
regressions were detected.
