Introduce DeserializeSampleValue() helper that enforces a 64 KiB per-sample
ValueBytes size cap before calling MessagePackSerializer.Deserialize<object>,
and documents that the default StandardResolver (primitive-only, no typeless
or dynamic-type resolution) is in use. Both ToSnapshots and AlignAtTimeSnapshots
route through the new helper. Add inline XML comments to the two NuGetAuditSuppress
entries in the csproj recording the advisory title, why each does not apply to
this module's primitive-only deserialization, and when to revisit.
