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

[KazukiKandaKK]

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 5a56398c975bfd9f328f544894bcb92533ed134c. The upstream script selected QuestDB 9.3.5.

• 43 queries x 3 runs
• 6,367 seconds to load the data
• 72,882,272,272 bytes after loading
• Queries 33 through 35 returned null in all three runs. Query 33 logged QuestDB's global RSS memory limit exceeded error; no kernel OOM or earlyoom termination was recorded.
• Concurrent QPS: 0.070, with an error ratio of 0.106

The result passes the current validate-results.py.
