Add Databend result for c6a.xlarge (2026-09-24)

[KazukiKandaKK]

Adds the c6a.xlarge result for Databend. The run used a separate c6a.xlarge instance (4 vCPU, 8 GiB RAM, 500 GB gp2) in ap-northeast-1 and the repository's standard benchmark path at commit fe9a4d9106bee37cebcbb984e44c9c7bd8776044. The upstream scripts selected Databend v0.9.53-nightly.

• 43 queries x 3 runs, with no null results
• 558 seconds to load the data
• 20,836,337,061 bytes after loading
• Q33 took 3,579.278, 4,689.898, and 4,604.563 seconds; the host used swap during these runs, with no kernel OOM or earlyoom termination recorded
• Concurrent QPS: 0.033, with an error ratio of 0.000

Validated the result with the current validate-results.py.
