Add GlareDB results for c6a.xlarge (2026-09-24)

[KazukiKandaKK]

Adds c6a.xlarge results for both GlareDB variants: a single Parquet file and the partitioned Parquet dataset. Both ran on separate c6a.xlarge instances (4 vCPU, 8 GiB RAM, 500 GB gp2) in ap-northeast-1, using the repository's standard benchmark path at commit aab0c029943296832b4812981e7fd401ffacc8fa.

• glaredb: 43 queries x 3 runs, 14,779,976,446 bytes
• glaredb-partitioned: 43 queries x 3 runs, 14,737,666,736 bytes
• Query 33 returned null in all three runs for both variants; the remaining timings are numeric
• These systems do not run the concurrent QPS phase, so those fields remain null

Validated both result files with the current validate-results.py in PR mode.
