test(codspeed): fixup #1153: open_and_close_vvmをignoreする

[qryxip]

内容

#1153 で用意したベンチのうちopen_and_close_vvmについて、これだけCodSpeed用の計測では凄まじく(具体的には±25%くらい)ブレが生じていた。そのためCodSpeedでの継続的な計測は不可能と判断し、デフォルトでignoreされるようにしてCodSpeedの対象から外す。

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

Summary

❌ 2 regressions
✅ 12 untouched

Footnotes

1. No successful run was found on main (148dc75) during the generation of this report, so abef143 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

2. 10 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

Pull Request Overview

This PR addresses instability issues with the open_and_close_vvm benchmark test that was causing significant variance (±25%) in CodSpeed measurements. The change makes this specific benchmark ignored by default in CodSpeed continuous measurements while preserving the ability to run it manually when needed.

• Adds configuration option to control inclusion of the open_and_close_vvm benchmark
• Sets the benchmark to be ignored by default to exclude it from CodSpeed measurements
• Updates documentation to reflect the new configuration option
