Fix bounded max partial state

[gatesn]

This is a breaking change to the serialized form of BoundedMax. The ZonedLayout change to persist these types hasn't been released yet though, so it is still safe to change for now.

In case of producing a bounded max value on top of another bounded max value we need to know if the original value was null or whether it became null after producing bound. It's safe to skip chunks in the first case but not in the second thus the zoned stats have to differentiate between the two

⚠️ 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.

⚠️ Different runtime environments detected

Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.
